Had my one amp in today to the co-incidentally local guy who is an amp builder and repair. Something is not quite right.
He always has some very good gear in for repair and of course lots of guitar amps.
In testing he took out the tubes and the Gold Lion 12AX7's test very strong. I have found the Gold Lions to be very dynamic and the Psvane did not test as strong although well within normal.
The EL 84 7189/6BQ5 Russian Preffered series ('80's military spec I am told) are a little weak after 1 to 2,000 hours in 13 months. New tubes Gold Lions coming. I guess normal for this type of tube.
One thing that did really surprise me one Duelund CAST cap was leaking oil and was wet. Not sure if this is what has sent sound off? It has not been tested yet as the volume control pot needs replacing on the amp and I will have him check it out then.
Now back listening to original amp that started this thread years ago. Just a dead quiet vintage amp that blew me away.
