1966 and built
many amps and so help me i can't seem to find this problem. I'am i the only one
having trouble
with this amp and this tube. i order one from rf parts and it was bad when i
got it. help
k5py.
If the amp is still in warranty, send it back to QRO.
When it comes back, sell it immediately.
If it is not, sell it for what you can get out of it, and take your losses.
There have been many problems with QRO. Several guys on the
East coast in particular.
I have had several conversations with the owner of QRO. His expertise
is in real estate, I understand; not amplifiers.
