Smile Single ended EL84 Schematic

Hi Everyone

I just purchased a mid 60's british made Robuk Reel to Reel tape machine
that has original Mullard Tubes: ECC83, ECL82 EL84 and a EM84 signal tube.
It has an early (looks like hand etched) PCB board but a nice tube rectified power supply with beefy looking power and audio TX's.
I think it would make a dandy little guitar practise amp. 6 Watts?
Can anyone recommend a good single ended schematic using the EL84?

I would recommend a first to find schematic for the tape machine you have, so you don't need to buy new parts for your amp.

I second Wavebourn's suggestion. See what you have and reuse them, this will save you quite a bit. But the electrolytic caps would need replacement though as they would probably be old and dried out.

With the tubes you have on hand, probably you can make something along the lines of AX84 projects. - The Cooperative Tube Guitar Amp Project
