|EBC41||detector and AF preamp,|
|EL41||as output amplifier,|
I bought this radio through Internet. The case was dirty and it had a few ugly spots where the finish was damaged. The previous owner did not know if it worked, and I was glad he hadn't tried. As a matter of fact, he couldn't, as the mains cord had been cut off.
As with the HMV1101, it was impossible to find any service documentation on this HMV1122. So I was on my own. But this HMV, too, wasn't too hard to fix. First, I had to replace the mains cord, the remainder of which was made of rubber and falling apart. Then I reformed the electrolytics in the power supply. They were still very good. I tested the coupling capacitor to the output valve and replaced it.
Then it was time to turn on the radio. It did work, but it was cracking badly. The EL41 output valve did not draw much current. I replaced it but my replacements were nothing better. I cleaned the pins of the EL41 and the EBC 41 to make the cracking disappear. Then I turned to the tuning eye, that did not react. Both the anode resistors had gone high, so I replaced them. Now the tuning eye was working again.
I finally degreased the tuning cord, which was slipping. After all this, I cleaned the case. This succeeded reasonably, but on some spots the finish had chipped off. Testing the finish I concluded it was cellulose lacquer. I decided to leave it the way it was.
So now it was working fine, but I decided I didn't find it particularly pretty. In 2006 I traded it.
