Thanks Ken.
I sent your info about the CT museum to a radio restorer friend in VA, and he just sent this back (his reply below). Sharing for those like me who hadnt heard of NCRTV museum. I also will likely be taking the Radio Repair Classes at CT depending on the drive and what the curriculum contains. I'd like to learn more around here but in ten years havent found anyone to collaborate on that, either tutor me for $$, or learn together (Although actually may have finally found some help this past week). So may be off to CT to jump start some training. Could be great fun. When I recapped and aligned that EC1A 3 years ago, it was very satisfying to bring in distant stations strong and clear, and even clearly listen to SSB traffic. The exercise also demonstrated the benefit of AGC circuit which the EC1A lacks, with an RF Gain control because if one SSB station is weak and talking to a strong one, the radio gets swamped and distorts on the strong one. IIRC I used a resistor on the antenna terminal that I could switch in when the strong side transmitted.

Someday soon I hope to understand how AGC is implemented and eventually be able to build a receiver then add that in and observe it working when monitoring a weak-strong QSO on SSB. Maybe that can be a future bench project at NEWSM as well.

 Thanks again for the tip.


Great Chris ------ looks like it is really well done.  We have such a museum in Maryland called the National Capital Radio and Television Museum:  www.ncrtv.org<http://www.ncrtv.org/>
which seems to be very similar - even to the radio repair classes and tube sales.  I just emailed your CT museum
