Hi folks,
I'm looking for help with possible gain/voice mods for a silver chassis EL34 Shiva.
Like some folks, I think the Shiva is awesome, but if I could just get 'a bit more'
I've been googling and searching forums and have gotten bits and pieces, but could use some help with details on how to apply them to the silver Shiva.
I'm working off this schematic snippet I found, seems a bit odd, but maybe good enough for reference

I've come across mods to preamp tube bias resistor/bypass cap - what I believe are called the Cantrell or Cameron mods?? - but they're for the Ecstasy
https://web.archive.org/web/2009042...0 ... dt967.html
I don't know which gain stage and what values work for the Shiva.
I also saw jumping R21, the 470k resistor between V2 and V3 to send a ~2x hotter signal into V3.
Any help would be greatly appreciated!
Thanks!
Matt
