    About 2 years ago, I sold my BC-610 E to a good friend here locally. I regretted it but I felt that
    my friend's ambition to finally own one was worth it. As time went on and as my friend turned
    80 years old, it was decided that it was time for the mighty 610 to return home.
    Happy to say the least.

    It had problems that developed over time and was one of the reasons my friend decided it was too
    much for him to handle.

    It's time to re-cap the audio and exciter stages as they are original but amazingly still function.
    I plan to keep it as stock as possible, but some changes are going to be made to make it run better.
    Once these are completed, it's going to be paired with a wonderful Hallicrafters SX-42 and
    matching R-42 speaker. This will become the daily driver rig for 75/40 meters and the Bauer 707
    for the night time boogie.

    The original BC-614 and cable are in great shape and many audio mods were done to the 614 to make
    it sound nice, and it does. I use a D-104 with very good results.
    Now, what to do with the HT-9?
    Catch you on the bands!

    The BC610 is a wonderful Tx. I used one for 18 months during my military tour at Naknek, Alaska, as KL7FAG. I pushed it to about 400 Watts with no problems. It always worked.l

    Quite a few on the air lately, along with a few T368's.
    I have a bc610 plate transformer on my basement floor, its one part that is heavier then a 32V3 or DX100 all by itself...
    It just sits there...

    Nice! Copied your power plug design on my '45 BC-610-E (blockoff plate over old AC socket hole in the chassis with a short length of wire & a 110V plug through a strain relief). Works nicely.

    Glad to see that this will be back on the air again. Fantastic vintage transmitters. Yours looks very clean and I note the filament voltage meter has a round gauge/bezel on yours like it is on mine (not square like many of the Es out there).

    The 610s work great, almost always (I've had two, both rock solid, and the other 610 owners I know have reported the same experience). The T-368s seem to be a different story. I worked through various mechanical bugs in mine (HV pressure contact issues, faulty relays, etc) and now fighting nasty hum on the audio. Originating somewhere in the speech amp or just adjacent I believe but haven't been able to trace it down yet.

    Hey Billy, make any progress on that 610 yet?

    Nostalgic simplicity.

    But I'd hate to have to attempt repairs on a BC-610E model, particularly beneath the top chassis section, under battlefield conditions while bullets and mortar rounds were whizzing by and exploding all around. A friend of mine modified his Model E by removing the cabinet bolts and separating the upper and lower sections, then installing a wide hinge across the rear of the cabinet, so the upper section could be lifted up and tilted back for easy access to the RF driver circuitry without having to disconnect anything or play contortionist.

    There was an E for sale in Michigan last week on Rig, speech amp., BC939, bunch of tuning units and coils, all for $1600. I thought that was on the high side but it sold pretty quickly. I think around $1000 would have been more like an okay price but maybe I'm out of touch. I thought just a 610 by itself would go for around $500. Of course the buyer may not have paid $1600...and there are a lot of variables.
