What intrigues me most about this is the fact that you just "found" it. I want to just "find" an amp like this

1979 puts it in MK IIA range for sure.
Upgraded to IIC spec? Odd.

Btw place the image links between img tags, doing so it's easy to place pics in a thread.
Definately a 60 watt

it does whatever the person who modified the amp wanted.....

take some pics of the chassis innards and post them...maybe we can figure it out for you.

it looks like it might have had a 7th preamp tube at one point. the pic of the inside of the chassis....wow. there's a lot going on in there. there's a lot more circuitry in there than a 'simple' IIA to IIC upgrade....

hi gals & guys ~

i recently found my IIC. its originally a from 10/10/1979.
there's supposed to be a pre-amp section of just 5 tubes in there.
this one's got a 6th pre-amp tube.

does anyone know what the function of this 6th tube is ?

thanks !

errrr... ah, well mine does too! It's in a black plastic factory holder. It's the spare!
SURELY you don't mean that one right? Are you goofing with us?

its located on the chassis's far right, as seen from the rear.
the fx loop jacks are at the right side, and right under that is mounted a 6th tube.
i'm actually not sure whether its got anything to do with the fx loop.
could it ?
