Re: Bass tube amp not loud enough
IT could be layout, it could be filament transformers,.. If it's modeled after and SVT, then the wiring layout is crucial. One misplaced wire and it will oscillate above hearing level and the amp will sound dull, and have no power. Absolute proper bias of an SVT is ridiculously important. IF your am...

Re: GONICH - a simple (Arduino) digital pedal switcher!
With the addition of another shift register, I think you need to extend the bit count.
instead of 8 bits, I think you may need 16 bits? i.e. 00000000 00000001 something like that.
I could be wrong.

Re: Elektronika - Synchro Wah [schematic]
I'm willing to bet a CA3080 is the can opamp. Or the rusky counterpart.

Re: Warwick Jonas Hellborg preamp
Yep!
I had the pro tube IV, but it had problems before I knew how to fix it.
The tube preamp section was balls out nuts though. =)

Re: Warwick Jonas Hellborg preamp
I DO have the other Warwick bass amp schematics.
Theres one that actually has a micro controller in it too. Something that now I kinda understand since I've been learning about micro controllers.

Re: Warwick Jonas Hellborg preamp
Well, I am waiting to see what I can get. =) Looking at the photo I can find, Yeah, Bass and treble I suspect are Baxandall But NOT discrete. I say opamp driven. As well as the preamp / gain stage. I also bet the midrange and mic in transformers are Sowter. The DI out transformer I have seen before ...

AGUILAR DB659 Preamp
Single Rack bass preamp from Aguilar. Discontinued and not very many made.
Another Fedner'esqe preamp, but some nice little ditties here and there.
I might build one for my studio

Re: Maestro FSH-1 / Oberheim VCF / Tonepad Filter/Sample/Hol [schematic]
I'll give it a shot. Never really did finish these anyways.
I wonder if a higher capacitance would work too, like 10pf or 100pf

Re: Ampeg - Sub Blaster [schematic]
You can put a variable filter in the tone control section, like EBS Octabass or the Aguilar Octamizer.

Re: Epifani UL501 guts
AH!! Cool! I had the Epi PS1000 for a hot minute, but did NOT like it.
This guy uses the Sanken transistors which are NICE!
2SA1295 and I think then the 2SC3858 or 2SC3264 compliment.
Thank you for the piccies!!!!

Re: Chunk Systems Agent 00FUNK! [traced]
Whats yer voltages?
I'm hoping that maybe its just a bad IC or two, but I just can't get it to filter.
