Hi, all concerned:

Tks all for the on- and off-reflector responses.

My answers to questions received after I sent out a bunch of jpg's, and my 
comments on reflector posts, are interspersed:

This is why I put the title in "quotes".

There's enough room for Y-K-I 455KHz c-w/ssb filters, my original intent, 
which are cheap relative to performance, to be fitted.  No need to go after 
filters to fit the 9-pin sockets.  It's "homebrew -15", remember ;o)

The set hears quite well on 40M.   I have not tried other bands.

I'm aware that it's bad form to fuse the neutral, as the plug this set's 
constructor used, all those years ago, does.

If you have the pics:

The "round white blob" near the power transformer (interior view) is a 
homebrew plug-in solid-state 5Y3.

The 3 2nd-i-f cans across the top of the interior view have pull-off covers 
over the tuning caps.

The "rectangular white blob" between the (perforated) l-o cage and the 
visible i-f cans is the bottom of a plastic bottle, and covers the 1st-i-f 
can.

The "red blob" is a caplug covering another tube socket.

The coil sockets are 5-pin ceramic.   Most, but not all, of the tube sockets 
are ceramic.

The S-meter is lighted.

The front-panel controls include (top-left to right-bottom by line):

 MODE: CW/SSB   (this is a pot)

PHONES/SPKR toggle, REC/STBY toggle, INPUT GAIN, main tune

RFG pot, 3-pos filters, RF AMP TUNING, 3-pos AVC, AFG/on-off

The rear drop has an @)239 antenna connector, a pot of unknown function, a 
fahnestock clip gnd and a binding-post gnd, a 1/4-in spkr jack, and another 
not-sure1/4-in jack.

Tks for reading, and 73,
