My take is a little different:ġ) Your speakers on an instrument amp (assuming it's a combo) are not appropriate for music. WRGKMC is more pessimistic than I am but his points are well-taken. and when it comes down to it you can build the Power amp and preamp separately. You can get them from china without tubes forĪ decent cost. If you already have two tube guitar amps, sell them and buy a botique tube amp kit. There are many out there that are very reasonable cost and it would be my best suggestion. Then it costs to buy a stereo tube amp kit.

In my gestimation, A pair of guitar amps isnt cheap and would cost you just as much or more to mod up a pair to act as a stereo Otherwise its cheaper to build from scratch if you cant use most of the more expensive parts in a guitar amp to get you there. You're going to have to do allot of digging to find something close enough to be worth doing. If its a high powered guitar amp something like Mackintosh used high powered mono block powerĪmps with large transformers. That alone is a tough task comparing guitar amp circuits to HiFi amps so you dont have to completely gut everything at a To get started you would need to find HiFi schematic that are close enough to the guitar amps you want to modify. The phono section would need to EQ the signal to RIAA standards if you expect the turntable cartridge to play backĪ record sounding anywheres near HiFi standards. Then you'd need to replace just about every coupleing cap in the thing so it would pass that higher frequency. Guitar amps roll off at 5~6K so you would need to tripple that responce. To line level and add another stage for phono level. You'd have to change the input impedance from instrument level You would have to completely re-do the preamp section and increase the fidelityĪnd frequency responce.

You may be able to find so paint by numbers mods that will let you turn a HiFi into a guitar ampīut its highly unlikely you would have any info on doing it the other way around. So my first question would be, do you have a matching pair of tube guitar amps to convert to a stereo amp? In a single chassis to doubble everything. Stereo is two single amps in one chassis and guitar amps wouldnt have the space Its totally impractical to make one guitar amp into a stereoīecause everything has to be doubbled. Which requires extensive electronics knowlege or some serious guidence.įor stereo you have to mod two amps not one. It is not something an amature is going to be able to do without reengineering the circuits
