Hi,
I put a pair of 572B tubes in my AL-811 amp and they died.
One went to a plate current of 600 ma and the other 75 ma.
Anyways, DX engineering tubes are coming.
I checked all my 572B tubes one at a time and selected the best I could for the
amp. The worst case sceneria was 75 ma.
Here goes.
600 ma
150 ma
85 ma
75 ma.
Am I going to trash my amp or will the output just drop?
It's holding at 500 watts right now. For 100 watts in.
So, should I leave well enough alone or should I only the 2 tubes in there as
soon as they arrive?
If one fails short could that take my amp out?
Best 73,
Alan
