[Hallicrafters] HT-37 Low Power Output

[Paul Adolph]

Hi,
I found this group and went through some of the archives. I have a couple of 
Hallicrafters receivers and 1 hallicarfters transmitter and found a lot of 
great information. I thought I would ask the group a question I have 
regarding my HT-37 transmitter.

I have operated the HT-37 for 3 years now and it has provided full output.  
I get great audio reports with it using a D-104 mic and I really enjoy using 
it.

I was using it this past week and noticed reduced output on the wattmeter I 
run it through. (the meter works fine with other transmitters). The 
wattmeter has a built in dummy load.  I have a frequency counter on the 
external antenna relay so I know exactly where I am tranmitting.  The 
transmitter meter seems to work as normal during tune-up on each band and 
the frequency counter reads the frequency but the wattmeter shows about 12 
watts out on CW,  5 watts out on AM and about the same on SSB when I talk 
into the mic.  That's on 80 meters.  The other bands the power is more 
reduced as I check through 40, 20, 15 then 10 meters.

I have never experienced 6146's getting weak or going bad so I don't know if 
1 or both tubes are bad or need neutralizing so I don't know what to expect 
from bad output tubes.  The problem could be somewhere else but I'm not sure 
where to look.

Other than the power output problem the transmitter seems to operate fine 
and if not for the wattmeter I would not know anything was wrong.  Do you 
have any suggestions on what could be going on with this transmitter?

Thanks for your help with this,
