Short story: Doing music for our churches fall festival in 2 days (10/20). Was planning on using new vta-st70 as amp. Was playing this morning and went to do last bias and one output tube is dead. No bias reading, and not glowing.
Amp is currently playing at lower volume levels and I can't even tell tube is out.
Is this dangerous to keep playing this way?
Would amp survive an evening at about half load?
Any emergency source of output tubes?
Do I need 4 matching or can I get just 2?
Thanks
Paul
