[ARC5] [Boatanchors] Update: BC-669 Project for Veteran, Parts Request.

[hwhall at compuserve.com]

If you still need them:- I can nab some 6SA7s, probably NIB too, from The Surplus Store That Refused To Die (end of month is the newest-last-day).  If they don't, my inventory claims I have 2 new + 2 used (it lies, sometimes).- I have a DC-34 xtal for BC-669 TX, 3995kc, if you want to mess with it.

Thank you all so much for your efforts, digging into those old boxes.
One of our kind members donated the glass 6L6s and another sent-
along a green pilot-lamp jewel to replace the improper white one.

Still need:
Two 807
One 6SA7
Frequency Chart Holder
Crystals for:
3880, 3885, 3890, 3495, 3500, 3505, 4265, 4270, 4275
(The BC-669 has a 385KC IF.  Someone get a medium to
raise the shade of the person who decided that so I can
throw garlic at him).
I'll be etching some crystals, but it's a tedious job and even
one off the "etch" list is a big help.  Last resort is
programmable oscillators, which I've done before and it works,
but a rock is better if possible.

Still need some suggestions for one or two 160 Meter AM freqs
that will apply to Texas.  Is no one on 160 AM anymore?
I once thought 1885 was the "calling freq" for AM, but I haven't
heard anyone there in quite a while.  Maybe my timing is bad?

Our Tug-Boat captain is excited that the project is progressing.
It will be cool to hear him on the local AM nets with it.
This one ain't easy:  Many grounds had gone Hi-Z.
Someone replaced the power connector with one from
an SCR-522.  The original connector is no easier to find now
than it was then, so I just "went with it."
Every paper cap in it, and there must be
two dozen, is bad.  Most of the resistors are over 20% out.
Half of the receiver tubes are bad, including the "gassy-est"
6K6 I've ever seen.  That one was an excellent example of why
one should not get lazy and skip the GAS test on the TV-7.
Transconductance looked peachy.  GAS test darn near pinned
the meter.  Oof!

What is it about the BC-669 that some of us find so attractive?
Maybe it's because it looks like something John Paul Jones might
have used to accept the surrender of /Serapis/ ?
