Marshall DSL 5C changing tubes

[bazzy]

Hello everyone;
I got a Marshall DSL 5C for home usage. I'd like to change the poweramp tube with SED Svetlana EL34 winged C. Is it possible? Is EL34 standard for the amp or does it have different types? I mean the pins or the socket on the amp. Thanks.

Not really. The EL34 is much bigger than the fitted 12BH7, uses a different socket and far too much heater current for the transformer.

Whew.
Not even close!
