Hello -
I have a question about my TL922.
When I tune on 80 and 160, the LOAD control bottoms out before I can
peak the power. The output power is about what I would expect so the
peak must be close but I am uncomfortable that the tubes are not seeing
as good of a match as they could.
The amp has always been real close to the 0 position but I don't
remember it being quite like this. To be complete, I have made the
following mods to the amp.
1. Inserted a HV fuse resistor
2. Directly grounded the 3-500Z grids
3. Replaced a blown blocking cap (1000pf). The service manual says to
use 2000pf but the operating manual says 1000pf
4. Replaced the tubes (unmatched)
The seems to work otherwise and has seen extended operating on the high
bands.
I would like to get the tuning back in range. Could any mods have had
this effect? Is it worth trying to add to the padder caps?
Thanks and 73
Tom W2SC
