Is there an error on the dri201 Marshall schematic ?
« on: March 14, 2023, 03:07:38 pm »
V7 Cathode on the dr201 Is connected to nothing

I don't belive It can function without to be connected somewere

Question is, is missing a connection to the V6 Cathode and they share the same resistor and bypass cap or each Power tube has his own resistor and cap ?

Thanks

Franco

drawing error.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

They were trying to save the customer 50% on EL84s - and keep the volume down.
