A Field Day Post From TC, WØEAJ - DEN

...and THIS morning, I listened to KØOJ and the AM net on a Gonset G-66 Receiver.  I got it at the Longmont, CO ham-fest; the guy had two - one he said worked, and this one "not so much"... I got IT and it's accompanying mobile p/s for $20... it looks as if it had gone through a flood or had been around some "wet".  I replaced the VERY difficult to reach "black beauty" caps, cleaned tube socket pin-jacks (a real bugger on 7 & 9 pin versions) [some of which were green], replaced one INCORRECT tube / I think he stuck it in there to make it LOOK complete... then had to try and guess which alignment coils were which, as those pages didn't download... I finally found another site which had the FULL manual (also, "not so much"), and did a cursory alignment.. maybe that's called a curse-o-ree one.  Got it kinda working... ultimately found that a .0033 tubular cap across the audio-output xfmr primary was buggered up, and the dropping resistor for the OB2 was essentially un-soldered (disintegrated solder joint) at one end... It's still a bit flaky, but worked pretty doggone well this morning.

Why'd I buy it?  My VERY FIRST Elmer; I mean the guy who FIRST showed me a real ham shack, was a chap named Carl Bruns (KØGOZ sk)... He had a '58 Buick Roadmaster (cool, in it'self), but it had a G-66 & G-77 matched pair (CHROME, yeah!), feeding a Webster BandSpanner - I mean, how cool is that - yeahhhhhhhh.  I always wanted one of these receivers... maybe because Carl had one, so now I got it... amazing critter, as it's 10 tubes, and TRIPLE conversion!  I've been running it with the Heath IP-17 HV bench supply... 12v filaments, with 210vdc @ about 70ma B+.  I still have to fix the BFO... it does work, but injection is very, very low, so I'm guessing there's yet another bad cap or resistor... or dirty pin.

TC,  WØEAJ - dit dit

PS - At the time I was sent the pdf of Carl's old QSL card, I'd just finished my 2nd. Valiant, and was LISTENING to an SX-99  (same as in Carl's shack, on the day I met him) - later on, Carl & his wife moved into a house DIRECTLY BEHIND my folks' - at 71st St, across from Antioch Middle School (Milburn JHS)
