This reminds me why i switched over to a Roland JC-40 from Fender Blues Jr after blowing up 2. I have never had one issue with the Roland, ever!

That Peavey is a prime condender for gutting the PCB and replacing it wirh one of your 5E3 circuits, make a 4xel84 version, volume, TMB and reverb , just 5 knobs. A smaller 3 spring tray for reverb , It would be better than spending 3k on new "Handwired" combo. Only mentioned it because I had the same priblems with a Fender blues Deluxe re-issue, got bored with changing speakers and valves etc etc so I gutted it but kept the Transformers. Now has 2 ecc83s and 2 ecc81s with 2 6L6s and proper spring reverb( 3 spring, small) an alnico Jensen p12q . Based the circuit on a 60s deluxe reverb without tremolo, very clean and zingy like a 40watt deluxe. I covered the tweed wirh a n amber coloured deck varnish( for boats, all I had in shed). Happy now, fuzz pedal works extremely well too. Have a great week.

You still have the power transformer issue which is probably prohibitively expensive to replace. IMHO better to enjoy it as it is until it fails then buy something else.

On your next batch of 5E3 amp builds , consider an offset mounting you speaket instead of the center. Fixed and done.

It IS offset already.

That brown glue on the Peavey gave me flashbacks to the the glue they used on Marshall DSL100HRs, which became conductive over time.

I’ve had my delta blues for ten years and the dude I bought it from gigged it for a decade. In those years we changed a pre-amp tube and maybe he changed the power tubes once. My favorite amp for certain. $300 and good to go.

I’ve got a 2007 Delta Blues and despite the terrible construction, and the noisy PT, I think the clean channel actually sounds quite good. Just going to play it until it dies I guess.

The Peavey Classic series had a pretty solid, working man’s amp reputation with players back in the day as I recall but that construction process is really off putting. I guess it’s taking influence from modern electronic manufacturing where things are made as efficiently (and as cost effectively) as possible with no thought given to maintenance or servicing. If something goes wrong you just throw it away and get a new one, and that’s a bit of a shame. That being said, Leo Fender was definitely looking primarily at efficiency and cost effectiveness when he chose to go with a bolt on construction method for his guitars. Make as many guitars as possible making use of unskilled (or rather non luthier trained) workers for as cheaply as possible. If you wore the frets out on a Fender the original intention was for you to order a new neck from Fender and throw the old one away. So I guess planned obsolescence isn’t such a new idea and Hartley Peavey was just following in Leo’s footsteps. If it sounds good then that’s the main thing I guess.

Hate those peavey boards mate, fortunately I get very few in. Love this chunky chassis on your Americana and 5E3. Love to know who does your chassis, they look top quality. 👌👍

hey up Chris! Great video as always always interesting to see the scale and variety of amp building techniques and approaches. Could you give us the heads up on the types of dummy loads you use? Thanks

@mikebarnard2689 7 ай бұрын

Well Chris , you had my little brain buzzing with excitement at the thought of that big alnico magnet sucking electrons towards it and causing all sorts of mayhem… of course 5 mins on an audiophile forum showed negligible effects of a stationary magnet to a thermoionic valve.. but thanks for wakening up my grey stuff. I’d love you to show a list of “ not worth the bother and time” to do jobs on various amps as 95% of owners or potential buyers of these amps have no clue about them being beyond economic repair for eg a cap job on that Delta. You wouldn’t have to denigrate any of the amps, just bring awareness of serviceability costs for common failures.

7:30 so, to create that custom 5E3 hand wired special sauce, how long do you have to marinate those pliers? 😂

I got a 210 delta blues with a sexy black tweed cover makes a horrendous racket you just broke my heart when you said you turn them away

@tobiasryan8378 7 ай бұрын

Hey Chris, I love your videos! Hearing your thoughts on the Peavey made me wonder if there are any other amps that you don't take on as a rule?

@waynegram8907 7 ай бұрын

How can you use and do to upgrade those jumper wires on the 3 sided PCB? there must be an upgrade

@caorach3354 7 ай бұрын

I'm surprised that some of the nice handwired amps haven't gone to using genuine Harris Tweed for the cabs as the Harris Tweed is available in nearly any colour variation you can think of and it is hand woven.

@sjgreaves 7 ай бұрын

I'm not sure if this comment was a bit tongue in cheek but to me the idea of a Harris tweed covered amp is hilarious.. How about some really vivid tartan? hahaha... Satellite amps have done some really cool coverings and even their more stock range have a cool sparkly covering. On my part, I covered my last head build with some upholstery fabric meant for a kid's chair or something, looks like classic comic book/superhero frames/cells, hilarious. Tolex can be so boring...

I’ve repaired and modded a number of Classic 30’s. I’d still rather work on one of these instead of a an AC-30

Tweed custom 50 owner, the reverb rarely worked. Sounds damn good otherwise

Chris, one for your Q&A? What do you use for cleaning sockets, pots, jacks etc? I'm guessing it's not WD40!!!

@ianminogue-corps7472 7 ай бұрын

I use Servisol for cleaning amp and guitar pots, works for me, not sure what Chris uses tbh

@seanblythe9109 7 ай бұрын

Chris, what signal/coupling caps do you have on those 5e3 boards? Panasonic? Looks really nice and I’m sure will sound beautiful with the alnicos!

@RiftAmps 7 ай бұрын

Yup, Panasonics, absolutely wonderful 🥰

i had one of those for a few years, put a JBL D130 in it and it sounded great, but yeah horrible construction made it not really a good long term amp.

@sjgreaves 7 ай бұрын

The power transformer issue is an interesting one isnt it? My understanding is that officially, to maintain compatibility of electronic devices across Europe, all devices sold here should be made for 230v but tolerate +-10% voltage differences, thus working in all European countries. (There is a government paper on this I found a while ago). This is probably why by default Fender amps sold in the UK are wired for 230v even though they do have a 240v tap (and is easy to fix by swapping some connectors on the PCB). While this tolerance might be workable for SMPS devices, for the simple transformer based linear power supplies most valve amps use it wil result in higher voltages inside the amp which at best is going to reduce valve life (probably). Joy... 😞

The Classic 30 & Delta Blues certainly have an awful design for repair - I just don't understand why they did that (and I've heard James Brown talk about designing it! There's a great interview with Dave Friedman & Marc Huzanski on Tone Talk. To be fair, James said Hartley told it it had to be "this big and cost this much") Having said that, I used one as my main gigging amp for a number of years and absolutely loved the sound of it and its playability. I have a Vintage 30 in it - which some people feel is too mid-spikey but I really like it. It only had one problem (due to a loose handle nut falling onto the circuit board) which needed repairing thank god! I think that the valve circuit board can get pretty hot and thereby damaged from the heat as well. It certainly went through valves quicker than my fixed bias amps too. The difference as I understand between the C30 and the DB is the DB has tremolo and comes with 1x15 or 2x10 as opposed to 1x12

The simple answer is cost of manufacture. They don't care about repair or life of the product beyond the warranty period which is not unusual in recent production electronics. Few consumers want to pay premium prices for more expensive construction methods that make repairs easy, for the majority of buyers, if it sounds good and the price is right then that is all that matters and to an extent I think that is ok, just dont expect the product to be repairable beyond it's warranty period. I've heard some manufacturers stop selling bespoke parts/PCBs after a while making repair difficult if not impossible too let alone the construction method. Like most things I think it is a matter of you pays your money and you makes your choice. If you want something that will be repairable in the future, go for something like Chris's amps which use essentially jellybean parts that will always be available and a construction method that makes repair feasible but be prepared to pay a premium for it. That is in no way a criticism of either construction type, just a statement of my opinion. If you look at other electronic products as an example, back in the day it was common for manufacturers to put the device schematic inside the device to make it easier for the repair person to figure out the issue. That has not been done for many years and in several cases the schematic can be very hard to come by. Manufacturers in general don't want you to repair something, instead just buy another one. This seems to especially be the case with the more budget end of the market and Peavey are very much at the budget end. That isn't meant to be derogatory in any way, just don't be surprised if you buy a more budget amp and the find it to be unrepairable a few years down the road - just enjoy it while it lasts!
