Got an old Fender Taurus solid state amp to work on here. Got it all fixed up and went to turn it on. From what I have read about all these old Fender solid state amps I expected it to just sound terrible. To my surprise it sounded absolutely fantastic!! It was absolutely silent with nearly no hum at all. It is a great clean sounding amp and I felt a need to post something to let other people out there know that it is not a terrible sounding amp. Of course someone had removed the JBL speakers so I had some old Fender 10" speakers waiting for just this problem. Somebody actually had installed car stereo speakers in the thing!  :trouble Also, the PCB board had leftover flux residue all over that had turned white. Looked like a bird had flown over it and took a dump right inside the amp. Anyway just thought to share this experience about this amp since it is a rare specimen.

Space inside the TOA probably won't be an issue..If need be I can drill holes in the base of the chassis and relocate things. Being from the 70s the circuitry is a lot more simple than today. The board inside the silvertone is the width of the input and controls but it's not very deep.i will put some pics up when I get everything opened up properly.

*Most*  footswitches , specially old style such as those, work by grounding the tip and sometimes the ring connector in a plug, in this case one or both "ears"  to ground.
This picture I found shows a 3.5mm "headphone"  one but principle is the same with a 6.35mm guitar one which I bet your Yamaha uses.
So get a 1/4" (6.35mm) stereo guitar plug, pull thye plastic cover, insert it in thejack you are testing and alternatively short either lug to ground with a piece of wire, and check for yourself what happens.

Then add wire as needed and a footswth at the other end, so yo again ground active lugas at will, just with your foot.

Then you mount it on a suitable, pedal type enclosure, such as the cast aluminumHammond ones or anything you can build.

No big deal as far as Electrinics, but youŽll have a *packaging*  problem.

Not sure the Silvrtone front panel and presumably full width PCB will fit inside the TOA cabinet and viceversa with the TOA power amp, power supply, heavy transformer and heatsinks.

personally I would build a powered guitar cabinet since ypu will need some cabinet anyway: build a 2 x 12" cabinet, maybe a Twin Reverb like side by side which will be some 65/70 cm wide, or one on top of the other, this time the same width of the Silvertone which I estimate in 45 cm wide, or thereabouts.
Same width (or slightly more) is needed so the Silvertone sits nicely as a "tall head"  on top of the 212 cabinet.
Then in the bottom of the cabinet backside you mount the TOA amp, as is, hardwired to the speakers, and add an input jack which goes straight bto the power amp input or some suitable Aux one.

That way for home practice or easytravel toa friendŽs home you just use thye light and handy Silvertone, and when rehearsing or playing LOUD you also bring the powered cabinet and join both with a Guitar cable. Of course each will need its own Mains connection, no big deal.

I suggest this because for Homebuilders the main problem is not the Electronics side but the "mechanicals" .

  I recently picked up a Yamaha G100 head awesome price and even better sound!
 I was wondering if you know or anybody on this forum would know how to go about making my own foot switches for this amp. Also have you found any literature on your amp if so where? Like an owners manual I believe mine is series 1 but I don't know for sure  how to tell.
  I was able to wire up one of my speakers from another little practice amp to tr out the head everything works I just don't have the foot switches or any info on the amp.
 Any info or help would be really appreciated.

thanks in advance

I think it's a great idea personally.  If power supply voltages don't work out, if you have room you could always move the power supply from the guitar amp along with it's preamp section.  Then just tap everything into the mains voltage and away you go.

Before any of my wild ideas with this I had gone back to basics playing around with pickup combos. 2 of my guitars I have played around with have similar direction but their own sound.
Dean MLXF - seymour Duncan dimebucker in the bridge and the original Dean DMT bridge humbucker in the neck position.

No name Les Paul - Bill Lawrence 500xl(neck) in the neck position and a DiMarzio crunch lab in the bridge..

It's those who dare to push it and experiment and come up with a signature sound that others would like to emulate ☺️

Could be an interesting project. I am experimenting with the chassis of a Dean Markley K-20 guitar amp, a couple of pedals and a Peavey M-3000 mono power amp as a bass rig, but what I'll probably do is combine the K-20 and pedals on a pedal board and keep the M-3000 on top of the speaker cab(s). This way I have the option of carrying the pedalboard back and forth from home to practice space, using the power amp and cabs with the band and driving a small practice cab with the K-20's 15 watts @ 4 ohms output at home.

I'm running an Ibanez compressor pedal in front of the K-20 and a DOD Bi-Fet preamp after it to slightly boost the low-ish line out level before the power amp;  the DOD's tone knob allows me to subtly tilt the EQ post-tonestack too, which is useful since the tonestack's EQ points aren't quite optimum for my bass tone. I get the gain structure and tone in the ballpark with the K-20, then fine-tune with the DOD.
