Freaking amazing, lots of notes though. And Marshall stacks, smoke and hair.

Hillsborough? You are very very local. Long time no see, last time was at Greg Buchalski's Ampfest. I sent a PM

Re: F*cking clients
Me: I should not have let you leave with your amp. This is where you screwed yourself. Learn, move on. We have all learned this lesson..... :oops: In terms of going forward, here is what i suggest; tell him to send the amp back in, if the repair you did actually failed, you will fix it. If its a new...

Re: 183(ish) build
Be careful with this here, the resistor will short once the conformal coating gives out. I would move it away from the nut. jelle

Re: Question on the #124 builds???
Yea, simply use 20uF caps for each preamp node. My guess was that the dual 10uF cap was available, and Dumble used it. It works, but a single 20uF works and is what one would normally see. Other amps had dual 40uF for clean and OD. Maybe that's what he had available that day. 20uF works well. have f...

3 preamp tubes: this means either no: Cleans, OD, PI or loop. Take your pick, lol

Re: First D-style (102) build opinions solicited & build thread:
The 100W ODS documented here (102, 124, and 183) all use 4k7 and 390 from the 4 ohm tap. A 50W adaptation would reduce the 4k7 to 3k3, or move the FB source the to the 8 ohm tap. Either way you will get the same level of NFB as the 100W. The resistor change results from using the calculation I post...

Re: First D-style (102) build opinions solicited & build thread:
So if I’m following this correctly for the sake of understanding the math; the presence cap would go from 2.2uf to 1.5uf? Also, what I’m gathering is that using what I already have - all I’d need to do is run the wire from the 4k7 off the board to the 8ohm tab on the impedance switch rather than th...
