[@Ireland831]

I remember I built a Blackface Deluxe Reverb and when I finished I had some noise and squeal when the amp was turned up. I tried lots of things...in particular I cleaned up my grounds and some of my wire routing and length and couldn't find it. I changed out a few items that I though would cure it, but had many hours of trouble shooting and couldn't figure it out. I ended up buying an Oscilloscope. I checked the signal at the output and could see the wave form get these weird spikes, (that I guessed was parasitic oscillation). I ended up looking at the wave stage to stage. 1st stage was fine - second stage was fine, etc. I forget the exact spot but it was somewhere after the second stage and it was right near around the trem circuit. Turns out I had scrounged up one resistor from my box of parts that came from an unknown source, but was my only one of that value I think it was the 4.7M resistor coming off the reverb feeding the grid of the next stage. Yanked that resistor and put in a new one and bingo! That was my first experience with a signal generator and an oscilloscope. Great vids! Keep up the good work!

Yah if there are strange noises and all the components check out, I’ll run the meter over the board to the lugs and see what it’ll pick up. You can take a hair dryer to the board and it’ll work to remove moisture sometimes.

Uncle Doug is far and away superior in electronics knowledge and the ability to teach it , but Brad has come a long way from his first muddling around in an amp. Brad IS a very excellent guitarist ...

[@tonyduncan9852]

@@jenniferwhitewolf3784 I couldn't agree more. But Uncle Doug's playing still sucks as bad as Brad's politics. (I know, one should never say so). They both aim for the same amplifier characteristics, and I sure appreciate that. I look forward equally to posts from both of them. I trained as a mechanical aerospace engineer in the 60's, and made guitars and amplifiers for our 5-man rock band when we couldn't buy them. We created 50W amps using EL34s and heavy duty twin-cone 12s in twin bass reflex enclosures, so Brad and Doug bring back many pleasant memories.

Well thank you, but Uncle Doug is and always will be the King of the amp video genre. His 30,000ft overviews of the parts of amps are a must-see for anyone wanting to repair or mod this stuff.

[@IndianaDoug]

To say Brad is the next generation after the Uncle Doug era, would be more accurate imo. Although, in your defense Tony, Brad takes on solid state flavors and more. So, I won’t discredit his abilities which are Fkn super good👍🏻

[@TonySkiens]

@@IndianaDoug uncle Doug is THE guru, don’t get me wrong. His series on the various components on the amp is the best there is. His technical knowledge his sense of humour his ability to talk in reality rather than theory is bar none. Since he’s covered so much ground in his videos he doesn’t like to repeat himself. You don’t see uncle Doug actually soldering anything anymore he skips all that and just presents his completed work which makes the videos very easy and fun to watch. My point is Brad still shows him mucking around in the guts finding the problems and then fixing them. Really a different genre altogether.

[@TonySkiens]

@@TheGuitologist yes very true. The fact that uncle doesn’t like to repeat himself he’s covered so much ground in past videos he just shows his completed soldering etc. We never have to sit there while he’s mucking around. It’s also great fun to see a guy really get into the guts of the amp to find its flaws. Really a slightly different genre you two. Very complimentary.

[@dank8865]

Aesthetically speaking, was never big on PRS guitars. But that red one is gorgeous. Like the old BÖC song, "...red & black, that's our color scheme". Yeah - hard to eff up with a red guitar, regardless of brand. Btw, that amp sounds killer & that's thru my phone. Can only imagine what it's like being in the same room with it & a good cab.

I had the same problem with a Silvertone 1471 found a grid bias resistor R13 that fed pin 4 of the 6V6 changed value from 4.7K to 3.5K and was probably due to arcing inside the resistor, replaced it and the amp quieted down. In electronics it is always stressed that resistors only open and capacitors only short which is generally true however you must keep an open mind. BTW, I bought a Baseman amp AB165 in 1983 for $35.00 at Imperial Beach Calf swap meet; still have it, had to reform the capacitors in 2007 using a light bulb in series feeding from the hot side for safety, started with a 7W and moved up to a 60W still using the amp today never had to replace anything except for tubes, thinking about adding the unused 2nd half of driver 7025 to get a Vox type of sound. There are a million of these amps out there so I would not feel bad about doing the mod.
