[Amps] Henry 2K Classic

[Jim Hoge]

Any thoughts on why my Henry has decided to operate as an attenuator? The tubes check out as good in another amp. The amp appears to tune and load. The relays checked out okay w/ only an ohmmeter. When under load, I am now getting about 20% of my drive power out as compared to standby where I get all of it. The amp sounds as if it's groaning when under load. Again, it's a Henry 2K classic (floor model) having left Henry's factory in Jan '97.

Tnx es 73,
