Princeton Rev Home-Build
I'm definitely new to this page. If I am out of line with my questions, layout posts or anything else please let me know! I have built 3 amps in the past. The latest was based off of a Matchless Spitfire. I have a really good clone of a 6G3 Deluxe, but despite my love for that rowdy circuit, I need something more versatile for cover gigs with a pedal board. I used to have a Blackface Deluxe (non-reverb), but I needed money after a divorce, so that went bye bye. I'm also looking for slightly less volume, hence the Princeton-based choice, and I've never built one with reverb before. I'm hoping (praying?) that someone here will go over my layout attached. It is based on a layout by Rob Robinette, who's site has done more to educate me that anything else I've stumbled across. I'm using his layout of the amp: https://robrobinette.com/AA1164_Princeton_Reverb.htm All credit and acknowledgement goes to him! What I'm attempting to do is modify and use an Ampeg J-20 board I aquired. It is definitely the right size but will have to have some new solder joint holes and eyelets added. What I'm hoping is that someone bored and curious enough, will go over my proposed layount attached in order to see if I have somehow failed to duplicate the circuit. (Yes, I know that is a PITA, but I'm dorky enough to do that, so I'm hoping someone else can double check my work!) Any connections in red/black would be new holes and eyelets.

Welcome! Why are there two layouts, side by side?

Re: Princeton Rev Home-Build
Howdy,
The one on the left is Rob Robinette's layout. The one on the right is my proposed "copy" of his but on an existing circuit board I already have. The circles in red and black are where i'd need to drill and install new eyelets in order to use that existing board. I'm hoping someone will compare them following the circuits to see if I have duplicated Rob's layout with the particular changes needed to adapt the circuit to the tan circuit board I have. It'd be a pain in the neck for someone to "circuit check" me, but I'm hoping someone more experienced than I will take the time to compare the tan circuit board on the right to the one on the left.

Re: Princeton Rev Home-Build
What type of cover gigs are you playing that a 18 watt Deluxe is too loud?
When I die, I want to go like my Grandfather did, peacefully in his sleep.

Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!

Re: Princeton Rev Home-Build
Oh! Basically all of them! I can't turn my DR build up loud enough to get to edge of distortion on stage, so I added a crossline MV. Works pretty well. (Sorry to answer for OP. Carry on.)

Re: Princeton Rev Home-Build
It's a good question Stevem. However, with the loud-a$$ drummer I have, it's all I can do to keep the stage volume reasonable. I always cover up half of my 1-12" cab with a guitar case! If I don't, then he goes into rock-god territory. I played drums until my mid 20's when my band indulged my dreams and let me switch to guitar. I know how easy it is for some drummers to let the volume creep up past reasonable....through palatable, but pushing it...to "my ears are going to ring tonight." I'm 64, but I was an early proponent of "WTF are we doing here?" regarding stage volume in the 80's. Consequently, I went from Marshall JCM 800 to a 50 watt 1-12" Ampeg, to a 40 watt Kendrick (5F6-A), to a Deluxe (both blackface/brownface). My drummer is older than I am, but he's determined to let his left (snare) hand rise above his chin when he gets carried away.

Re: Princeton Rev Home-Build
Had a quick look. I don't know if there will be any issues due to the layout itself, likely not because it's pretty similar and more space between some components.
The only things i saw were the 120P reverb cap is floating on a lead, in the original it had an eyelet to tie it down, and the coupling cap coming off V2 pin 6 is not connected to the PI, just a bit of wire not drawn.
Why are you reusing this board tho? It seems like a lot of effort to depopulate and clean the board. Also, this board looks quite a bit longer, if you are using it in a PR chassis, it will probably interfere with the cap can. An eyelet board for this layout is <$20 from Amplified parts, and Hoffman's upgraded turret board is <$50. It seems like you would spend quite a bit of time, plus $10-15 in desolder braid, supplies etc... to clean this up.
