    Micro Bassman LTP issues

    Hello sir - I just posted the functioning voltages for the amp. They're pretty similar to what I had before but definitely some differences. This thing sounds great - thanks again for the help! I couldn't see how to edit the initial post (not sure if I even can) to reference that the correct...

    Micro Bassman LTP issues

    Okay so unexpected success… I was doing some cleanup on the amp and all of a sudden it roared to life and is working with no oscillation… I checked it left, right, upside down, and sideways over the course of about 30 hours and I didn’t find any shorts… but my guess is that I nudged something...

    So guitar signal is NOT passing through all I can hear is motorboating/oscillation. All heaters glow the same, yes. And finally I do have another 12ax - I’ll pop it in now.

    Micro Bassman LTP issues

    Great input thank you - so I’ll reconnect that wire and remeasure just V4 again correct? Funnily enough that’s the way I did it first, I just thought it was an error so I undid it.

    Micro Bassman LTP issues

    DISREGARD THE B+ AND PIN READOUTS HERE AS THE 820ohm CATHODE WAS DISCONNECTED FOR READINGS. PROPER READINGS ARE IN POST #15 Hi everyone - I just took the measurements. To confirm: any test connections have been removed and the amp is "stock." The only thing I am not sure of is the 820Ohm...
