This V4 could be recapped a few ways. I was hoping someone here has a regular/standard go to list of parts and any hints to make it go smooth... It has the original caps. A Beast.....

Schematic & a picture of the chassis? If we know what we're looking at physically... And most guys here DO so much they don't memorize anything or particular amps...
I did a VT22 last year, had to do quite a bit of improv to avoid spending more in caps than what the amp cost the owner... Yes, a beast. Best played on 10.

I usually burn through my can cap clamps replacing the chassis mounted ones with standard 50x50@500v caps.
Sprague 20uf@600 for the series mounted cap clamped to the board.
I could have sworn I had another clamp while working on another amp and sure enough after I ordered more I found it.Comment

For V4 and similar, I use film caps for the highest voltage nodes, now I don't need to wire a pair in series, that's one advantage. Got a deal on some 30 uF 800V rated ones so I put 'em to work. Granted they are rectangular and sure don't fit into holes for the cylinders you're replacing. I fit them into the rear corners of the chassis, glue them in place with epoxy plus wedge them in place with plastic foam insulation blocks. Once wiring is soldered into place, I clip off extra terminals and put a dab of silicone RTV on each terminal for safety.This isn't the future I signed up for.Comment

Interesting, most cobble together their favorite caps configured to get the job done. The high voltage just make more work. WHAT? V4 on 10 ???? Thx for the replies......Comment

V4 on 10? It's not <THAT> loud... I had a Super Twin on 10, too. I didn't say I was playing in a band with it or that anyone else needed to be heard. I would never do that. But, it's worth the experience even if only once.

I use CDE snap in caps from Mouser. 380LX? They will "snap" in to the bottom hole on a Keystone terminal strip (maybe others too but I haven't tried). You'll need to use an extra nut to lift the terminal strip off the chassis a bit. I keep the original cans in the amp, disconnect them, and drill out the rivets. I use the rivet hole to bolt in the terminal strips (5 lug/center ground - mouser part # 534-817 ). You can get two caps on one strip and can also mount the necessary resistors across the top of the strip. It keeps the original look and doesn't cost near as much as drop-in can caps.Comment
