Hi there,

I recently bought a 3-knob Sola Sound Tone Bender MKV, the last of the sixties tonebenders.

It's the one in the narrow yellow box with black & red lettering and first time the fuzz "Batman"-logo appeared. Under the footswitch there's the "HIT IT" logo

Now i found two unmarked iron transistors in it but the third is a black plastic transistor model C5598 PH61. Is this a silicium transistor??? The person i bought it from never changed any components and he owes it already a long long time.

Can this transistor be original???I can try to make pics if someone wants to see it.

Does somebody haves the schematic of the MKV.

All help would be very much appreciated.

Greetings

Ronny
