I love that guy's playing.
His latest album is great!
Not sure what the guitar is that he plays but it has a humbucker in the bridge and singles in the middle and neck.

Re: Tight/Loose Switch--Worth the Effort?
Thanx to all for your notes and suggestions.
On the point about load sharing, despite the two load balancing resistors, if we assume the ESR of the piggybacked 100uF caps is different from that of the 220uF caps, which is reasonable, then I can expect load sharing problems, I take it.
I didn't think that through before I did it. Looks like I'll have to start again. I do have some big high voltage radials.
I already modified the board to split up one of the paired positions so I could use two 22uF/450V caps sequentially for the loop buffer tube supply. It is one of Jason's boards, it has the extra pair for a buffered loop or a reverb supply. I'm not sure if he still makes them.
The two diodes are IXYS 1200V 15A soft recovery FREDs. I like to use a dual 1200V 8A FRED in a 220 case but Jason's board is set up for individual diodes and the ones I used are the only ones I have that would fit the anode & cathode hole spacing. I have some 1800V 2.3A but the lead spacing is wider.

The EG model has freds in there too along with the 100uF caps.

I got some Nichicon 100uF 350v radials that are actually a little shorter than the 47x350's that will follow them to use in my el-34 amp that I'm working on.

Making my own boards and I'm a cheapskate, so radials for me...

Radialized!
I had a pair of Nichicon 330uF/400V which I fitted and wired up under the board. They are 100mm tall and will only just fit in the chassis with the board on 1/4" standoffs.
They measure at 155uF in place so they are about 310 each, not 330.
Nice thing though, now all the caps are Nichicons except the two 22/450 Rubycons, which are the slightly fatter small pair.
