Dead Vintage Ibanez Pedal...Can It Be Fixed? - 1982 Ibanez PT-9 Phaser

Guitar pedals are usually such low cost items that fixing them, or having them serviced or repaired by a tech is prohibitively expensive, but some new and vintage pedals are valuable enough that replacement cost would exceed repair cost. Is this c.1982 Ibanez PT-9 Phaser pedal repairable, or will it end up in the trash bin? If we can fix it, we'll give it a demo at the end of the video, so stick around.

Try to put a normalizer or limiter in your editing/audio software, or if you can find a way to get the waveform (RMS if possible) of the whole vid , that's the best way to see if you've got a volume jump

Nice job Brad! My dogs send you their sincere thank you for fixing that screech! Interesting on the battery connector, I've never used batteries in it, always power supply (which is in the junk pile now).

[@russellhltn1396]

It had an external power connector, but it looked pretty rusty. I was wondering if the problem would turn out to be a bad switch in the connector causing poor power.

[@Dr_Satan]

The back to back 47uF are a way to make a bipolar cap without using what used to be an expensive part. Those 2 caps do the job of one 22uF bipolar cap.

[@russellhltn1396]

Exactly. From what I can tell, they are in series. Putting caps in series decreases their value. So two 47 would be 23.5uF. (22 is close enough). And since they're for audio, not power filtering, you may not see any voltage on them. Some op amp designs will have both the input and outputs at 0V DC.

[@TheGuitologist]

What was confusing me is why on the schematic they had two arrows both pointing the same direction.

[@68MalKontent]

These are not arrows, these are plus signs. Voltage in the op amp feedback loop swings both ways, so a standard polarized electrolytic cap is not a good idea, so they use a reverse-series connection which results in a makeshift non-polarized capacitor. However, electrolytic caps like to work with a DC voltage component applied to them all the time, which in this connection is obviously impossible, so they will degrade over time much faster than usual.

My local guitar shop, "Guitar Jungle" at Redfern N.S.W. gave me an Ibanez Stereo Chorus as a bonus when I purchased a BOSS SD-1 a couple of days ago. He said it wasn't working and he coudn't be bothered fixing it. I came straight to your website and it looks like the " Tone Home " web site may have the answer. Thanks.

[@CPUTests]

That board is like that because it was destroyed by the electrolite that came of some capacitor. Some capacitor had leaked out some of that corrosive substance on that board and the disaster is done. But as always you've been able to save it and bring it back to life. Thank you for your very good work. Best regards.

[@DonCrowder]

Those two electrolytics in series amount to a 23 uF non-polar capacitor. Whether the negatives are tied together or the positives, it amounts to the same thing. Just noticed that someone else made the same observation but I'll post this anyway, by way of confirmation. :)

[@arensel84]

Definitely do more pedals! Love seeing you demo them after the fix. A lot of old pedals have died from crappy components. The ones that were point to point would be easier to work on than thin cheap printed boards. Keep it up!

[@SnahLhug]

I've worked on a lot of old machinery control pcb's, and they are very frail like this one. Using a solder sucker is a quicker job and helps avoiding those paths from coming off. One has to be fast in and out so that components don't get heated too much for too long. Solder points should be taken out in steps, specially the bigger ones. Low wattage or temperature controlled soldering irons can help.

[@SnahLhug]

Although keeping those suckers clean and properly lubricated can be a nasty job

[@s10belowu]

I was going to say the same Thing. A desoldering pump is great for not burning up the traces in those boards. too much heat with braid will surely toast them and you hand wiring it from the back. $8 on ebay maybe less. get the spring loaded one and not the bulb that radioshack has for like $2

[@TheGuitologist]

Thanks for the comments! I have a solder sucker. A couple of them, in fact. In this case it was really a matter of no good solution. That board had already been worked at that point by someone or had gotten hot and because of age the traces were delaminating and falling apart. You can see sort of early in the video where the green protective covering on the traces was rubbed completely off in spots and the traces were bare. Any working on those whatsoever, even with a pump, was going to mar them up. I replaced several other caps on the board and didn't have trouble, it was just in that one spot.

[@russellhltn1396]

And some board are just junk and will come apart anyway. What size iron were you using? A good iron for "rat's nest" wiring may be too strong for delicate PCBs.

[@joshmakeshift]

i do as well. old diax stuff... i wont touch it without a sucker handy.

[@RiffHarvester]

My buddy gifted me with a malfunctioning Ibanez TS9DX pedal. It was squealing just like this and kept cutting out with tiny bumps to the pedal. I took it apart and didn't see anything that looked damaged. Since I didn't know much about electronics or pedals, I put it back together and left it in a drawer for a couple of years. Fast forward to 2020, I know a little about pedals now so I took it apart one more time and put it together, and amazingly, it works fine now! I think it may have been shorting out somewhere inside under the knobs because I noticed that the pedal started playing correctly after seriously tightening down the pot nuts.

[@DoRC]

In a situation like this where there are only a few caps that are easy to get to and the board is older I suggest just changing out all the caps without even wasting time testing them. Especially being off brand if they aren't bad now they will be soon.

[@TheGuitologist]

Well, they are Nichicon, so good brand, but you're right, all the polarized 'lytics got the boot.

Good plan, except when the board is delaminating.

When I sent my Cs9 to get repaired ( one of 2 instances where I swallowed my pride and sent it to a smarter tech 😕)I thought he had "bloobed solder as well. But honestly Ibanez has crammed SO MUCH onto these pcb that the components themselves are kind of blibbed together. I wish they would have just sprung for a complimentary enclosure

[@ConkysGhost]

I've had one of these Ibanez PT9 Phasers for about 25+ years and it works great. Bought it as a Secondhand music shop. I wonder if this problem is lurking around waiting to pounce.

I learned how to repair effects by putting an ad in a local paper " Will buy any guitar/bass pedal in any condition for $20" I got lots of takers. I learned how to trouble shoot and repair them. Lots of stupid simple issues were easily fixed. This phaser sounds great.

I'd still let them know about it. They might give you a gift card or something.

[@kenpowilliamson]

Thanks for the reply. I will most likely let the repair department know of the issue and give them your link to this great info on what to look out for on known issues with this particular pedal. ;) P.S. you were spot on, my issue was in fact the 47 uf @ 6.3v electrolytic next to the feedback trim pot. The two large 47uf 10v caps were fine and measured about 52uf each but I replaced them as well. The P.C. trace between them lifted and I just used the leads that connected them on the new ones to each other as a strong bridge. Thanks again.

[@Bencarelle]

IDK if anyone said this before, but the caps at 14:40 are probably like that to create a non-polarized cap in the feedback path.

It had been mentioned, yes. And DUH! Of course I should have recognized that was the case. Forest for the trees.

If you are desoldering components for a living and time is money, you will really appreciate a powered vacuum desoldering tool like the Hakko 808. Trust me on that. The thing you have to watch out for is sucking strands of loose wire/lead . That will probably jam up the tube requiring you to clear it with the wire rod.

Pedals are either great to fix or a pain. I have a Line 6 HT distortion, a nasty mix of a 12ax7 and modern surface mount devices... apart from discharging the valves psu cap with my finger a couple of times it seems to be more of an issue with the modern side. I'll fix it one day. Some of the prices that are charged for brand name pedals, let alone the boutique stuff makes it worthwhile to fix but you get caught out by the obsolete ic's. I'm also working on a pair of Boss ME-10's from the 80's which are also a pain, you fix one bit and then the next part of the chain dies. Anyway, be good to see more pedal stuff. Thanks for the video.

[@TheGuitologist]

Anything IC or transistor is very touchy. Voltages want to be in a narrow band, can't handle spikes, one part goes and transistors sometimes don't survive. They are a PIA, for sure. Give me a tube amp any day!

[@wildbillhackett]

Really? SS amps are tougher to work on? I assumed they would be easier. I know op-amps commonly blow, but it was my understanding that op-amp technology hadn't changed much the past 40 or 50 years, so I figured this meant they would be easy to find replacements for. Regular transistors too. I know Uncle Doug refuses to work on SS amps altogether, so what you say must be true.

[@audiotechlabs4650]

The Guitologist Man I TOTALLY concur! I have a Fender Champion 40 I'm going to(if I can)keep the effects and the rest will become a BF Deluxe Reverb. Tubes, tubes, tubes. Nuttin' better! Thankz

[@TheGuitologist]

I have been consciously making myself work on more of the SS stuff to get better familiar. It's outside my confort zone, which is precisely why I need to do more of it. And yes, it's more difficult. Tube stuff is very tolerant. You can have voltages and biases WAY off and stuff will still work. I can listen to a lot of noises a tube amp will make and have a good idea what might be causing it, but this screaming siren whine stuff...not really.

Coming in very late to this video... but nice job. I understand the challenges, as I have been given old pedals to repair that had traces that were eaten by moisture and time and had to be replaced by wires running to and fro.

Again... nice work.

[@TheGuitologist]

I checked the voltages at the test points and those were all ok and rather than digging out my scope which is buried, I started testing components - transistors, diodes (all good), then just started replacing polarized caps, checking the pedal after each one. That 10uf beside the Feedback adjust pot allowed the pot to dial out the squeal after that. Sorry for that clunky edit.

[@sophiemilton5939]

There are non-polarised electrolytic capacitors which are often used in crossover networks. They tend to be expensive. Putting two electrolytic caps in series in that way, linking either the two -v or the two +v together produces a non-polarised capacitor. (- obviously, you need to double the cap values as caps in series divide in value)

If the power supply filter capacitor is bad, it allows feedback to cause oscillation. Also the fluid in an electrolytic capacitor leaks out it is very messy.

A rather easy fix, and very well explained...a super-awesome technician, however the solder looks cold and in blobs.. and the board scorched. (a large area, and we all know cold solder is unreliable) Brad, you're better than that. Your tip isn't clean enough, and too hot!

What was the cost of repair vs just buying a new pedal? Diag and labor probably cost more then the pedal.

[@stevehovey70]

Brad.... Japanses transistor part number standards use the 2Sx prefix for transistor part numbers. If the transistor starts with a C like on that pedal... it is a 2SC2458 which is an NPN. C and D are NPN and A and B are PNP. Transistors that start with a K are usually digital switching transistors.... NPN or PNP transistors with built in bias resistors and are usually used on 5V logic circuits. example datasheet for the 2458 resistor: www.mouser.com/ds/2/408/6517-5372.pdf

It's funny because I had the exact same pedal I still have it!... and I never could resurrect the thing because too many of the parts were bad and they were just impossible to find exact replacements for. But I had the whole thing where I was wondering what the heck was up with the capacitors and then realized they were put together in a bipolar configuration and that you're dealing with the phasing effect so bipolar or construction is the whole basic concept behind phase oscillations and and you're always going back-and-forth between in-and-out of phase so having bipolar capacitors and constant sweeping of phase and out of phase relations is the whole rule of order for a phaser. It bummed me out because I really like the way they sound! they are a high quality phaser and with a lot of adjustment and sweep... you can really get a great sound from them but the one I have is just toast unfortunately... But I already lived your whole episode here, lol.
