[AMPS] Re: Old Henry 2k

I purchased for not much money, a Henry 2k that was probably made about
1964. It still has 3B28 rectifiers and 3-400z's. I spent a day cleaning
the RF deck which was more than dirty.
One of the primary fuses was blown when I picked it up. After cleaning and
looking it over, I applied HV with no big problem. The rectifiers glowed as
I remembered from years gone by.
On removing it from standby, the tubes idled within specs. The problem
occurred with drive. After about 400ma (just a guess) the first time, the
fuses popped. They blew big time (glass cracked). As the glitch occurred,
I could hear the transformer rumbled from the demand for a lot of current.
As a test, I replaced the tubes and ran into the same problem. This time
putting it into the transmit mode with no drive, I could hear the
transformer rumble again intermittently. Driving it with 10 watts, the
It appears to me that the plate transformer had been replaced. I was told
when I bought it that it was a Dahl transformer. Any ideas are welcome.
