I’m not knocking you/it just to be clear, but he has pretty damn good ideas, the friend isn’t some schmo off the street amp guy lolpsychodave":3444rb96 said:paulyc":3444rb96 said:And the friend is MC, don’t leave that out...
Indeed. He never modded one so he gave me ideas and I had to test out lots of things.
If you look closely, I even changed out the output transformer. It made is sound smoother/better. I’m also running NOS Russian 6P14P EL84’s (I like the non-military version the most). I bought a shit load of them from someone in Europe.
Sounds good to me..I might just buy another one and send it to BFG and let him do his magic.psychodave":2h37lslf said:riffermadness":2h37lslf said:I modded a Custom 22 and it didn't sound as good as this did..can you tell where or how to get the Jose mod for the JCA20 ?psychodave":2h37lslf said:I had such a hard time with this topic. I love my 100 watt amps, but playing st super low volumes all the time was kinda a waste IMO. So I got a JCA20 and modded it into a ripping Jose type amp. It sounds amazing at all volumes.
The Custom 22's board was tricky doing mods to without pulling out tracers and the pads,I barely put heat on a couple of them and the traces pulled up,had to do some serious repairs but I fixed it,and then sold the 22..and it really sounded good with preamp tube swapping.
I did the mod myself with a friend feeding me ideas. It really wasn’t simple. I have mods in both the preamp and power amp section of the amp. Lots of little tweaks to get that tight yet massive bottom end out of el84’s and zero fizz. I am using 5 volt zeners in this clip.

Ironball is tight enough, but still juicy. More akin Powerball II than Powerball I. I get the impression from some reports that the Thrasher may be too tight and lacking lows.

10n output PI cap?!
Would you check the ot reference plezse? Probably a typo, that ref you gave doesn t exist
nico22":24m0mxi2 said:those little phones with ours big fingers
Also maybe a typo the 22n coupling caps? Maybe more 2,2n...?
nico22":n54q95bu said:yes that's why i asked, 22n both coupling looked too much, compared with the sound of your clip.
You put 220k first R plate because 330k was too fizzy maybe?
nico22":20en5fu2 said:maybe not enough preamp voltage? Did you try to lower the dropping power resistor?
