Got myself an early Soldano sp-77 series II preamp in a very slightly purple finish. I just wanted to say how much I enjoy it compared to the Yamaha T-50 I have been working on and off over the past couple years.
I have found the schematic but it's a little different in layout from what I'm used to.
I'm about to sell off the T-50, though it has good iron and a nice layout/ footprint.
I have an idea to convert the T-50 pre to the Soldano design. The power amp sounds great. I'm just thinking about the PC board. Is the design close enough to mod the pc board or do a new preamp tag board ?
I'm just thinking that the last few Soldano designs I had looked at were pretty similar in layout. Like two of the three channel preamp channels and the two Yamaha channels.
Good time waster ?

Re: Building Soldano style preamp in a Yamaha T50
I always wanted to play through a Soldano.
They were the king of lead guitar was I was younger.
Not sure I would want to build one though.
He uses quite a few Vactrols in his design, not sure if these are easily sourced.

VTL5C1 are easy to be found, but they are costy.
But it's possible to build a SLO100 with something like 600 bucks.
Chop, what do you want to obtain exactly from the T50?

I did the mods Roberto suggested and can say it helped but I don't care for the character of the amp. Just really harsh. I have used the power amp to slave into and that sounds great. The problem as far as I can see is the preamp character. I believe everything is working correctly . No odd noises or behavior.
I wanted to try to keep the switching system and change the preamp to more closely resemble the SP-77. I like both the clean and the drive channel. Maybe delete the reverb, possibly for an effects loop.
It just seems that for the $350 I can get for the amp, I could use it as a cheap basis for a soldano type sound. Transformers, chassis cabinet hardware and PS is the spendy part of a build. THe preamp is all labor and maybe $50-70 in parts. (staying with good but not crazy expensive parts).
I'm not familiar with the SLO sound but I like this preamp plenty.
