'76 Marshall 50w

This is my 1976 Marshall 50w 1987 model. This amp originally came with 6550's, but I changed to EL34's because I like the sound much better that way.

• V1A cathode .68uf/2K7;
• .022 1st stage bright coupling cap;
• No bypass cap at V2A;
• 1k Rk at V2A;
• 33k/470pf tone stack combo;
• 100K NFB resistor connected to the 8ohm? tap;
• .022 output coupling caps;
• 220k bias splitter resistors;
• .1 cap and 4.7k on the presence control;
• Plate voltage is 395v;

These are the original transformers.
