The tube arrived in the post today. Plugged it into the base and........... it works.
Was hoping for something more exciting I suppose. Just bought a $300 amp for $60.
The volume potentiometer is bad though and a few others too so I'll replace them in time.
A pic of the two tubes. The pink Lines mark points in the Glass where a blackening is on the old but not the new. They are both 12ax7 tubes.

thanks for watching
Your Marshall 8080 is a good two channel 80 watt amp
ReplyDeleteThe 12AX7 or ECC83 is a minature dual triode with an amplification factor of 100. Very popular in audio amplifiers and audio stages of radios and televisions form the old days.
