Perhaps the positive feedback that makes the vertical oscillator oscillate has failed and the synch pulse from a program is all that is exciting the vertical output...

Have you ohmed out the vertical blocking transformer yet?

Those are beautiful sets, Tim. The DuMonts are always impressive looking, and are built like tanks. No cheap plastic in those babies!

I also managed to grab this in the ETF silent auction for $20 :)

BigaudioAl is getting this one too....unless I decide I love it ;) :D

I have NO space right now. :sigh:

She's yours!!! :thmbsp:

Much to my surprise, the chassis was totally recapped, and some new resistors in place. Only problem is that the 19AP4 is stone dead. Did I hear someone at ETF mention that the museum had some for sale?

Anybody here have a WORKING Royal Sovereign ? THAT would be a site to behold.. Too bad their reach kinda exceeded their grasp..

The ETF did have 2 19AP4s for sale. Did. I bought one of the two and someone else purchased the other...
