    So have I mentioned just how sick of smelling PAINT I am at this point? :)

    Just finished second coats on the last four boxes....

    So in total:

    SB-3xx type hinged boxes: 4
    SB-600 type boxes: 9
    SB-650 boxes: 2
    HR-10/DX-60b boxes: 2
    HG-10b box: 1
    HD-1410 box: 1

    For a total of NINETEEN Heathkit boxes went through the garage, all IMO as close to original as possible - stripped to bare, Zinc Chromate acid-etch primer, Rustoleum Hammertone base coat for texture, 2 final coats Heathkit SB green and dark SB green. I'll have spares of both sizes - only need three of the larger and only five of the smaller. I just stripped and painted everything I had so I only have to do it once!

    Now they'll sit - for probably two weeks - just so the paint can cure fully. I've learned very hard lessons about putting gear in newly painted boxes too soon. Patience is very very much a virtue.

    Paint "booth" comes down tonight, just in time for new kitchen cabinets to take up the space for our new kitchen project.

    Note too: I now have a SECOND SB-650 due to another local generous benefactor. Will post such in the SB-650 thread tonight. That explains why I just painted a second SB-650 box :)

    I'm actually considering that for one of the two SB-650s I now have! The first one is seriously tempting to consider, because the Nixie socket traces are trashed. All I would need to do is pick off the BCD chip into an LED driver to the readouts.

    Thanks for posting those sockets - that would be perfect for the task....

    I'm revisiting the 650 (x2) project later this week - and make a decision on which way I want to go, now that I have TWO of the things!

    My suggestion:

    Press on with making one SB-650 as original as possible - Nixie tubes, patched-up PCB, etc. One good unit from the two hangar queens.

    Then, if that's not enough, make an "SB-650A" - an improved version, with LED display, new PCB or perfboard, revised power supply (no need for HV), etc. , which can be used with the S-line same as the original.

    Or, keep what's left as a parts source.

    IMHO.

    I mean, if all you want is a digital dial for the SB-line, there are easier solutions. But it's not about "easy".

    What kind of shape is the second one in?

    Yep! It's about the K1T project and something of a "Heathkit SB Dream Station" from the era. I will most definitely be selling off much of the SB station after K1T is over. I'll likely only keep the SB-101, SB-640 and SB-630 and sell all the rest off.

    I'll revisit the SB-650 thread later today when I'm back in town and post pix. But it's in pretty good shape - the MHz Nixie strip has issues - when it powers on, the Nixie lights for 1/10th of a second then goes out. But it's vastly better than the water-damaged one.

    Watch for updates in that thread later, with lots of pix

    Well now that the sad tale of the SB-650 has come to a close, I can get back to the larger project: K1T and all the Nekkid Heathkit Boxes.

    So first batch is in beautiful new-looking boxes, with all new feet, screws, and lid-hold-down screws.

    Quite a sight to see indeed! I've never owned a complete SB-401/SB-301 with SB-650 station before! I can hardly wait to get it on the air - hopefully fairly soon. Just need to alter the main operating position infrastructure a bit.... I'll be pulling all the modern gear to make room for complete Heath coverage. The 301/401 will be used 100% for CW, the SB-101 for both CW and SSB.

    Anyway, for now they'll live on the bench for a while - going to get them on the air from the bench first, just to make sure everything is all in order.

    HD-1410 - nice little keyer but I wish the weight they used was a bit heavier.... but backing off the springs makes for very easy use. Looks NICE in the repainted cabinet - originally was very beat up.
