[ARC5] FS: R-27 and BC-454-B receiver combos

[Dennis Monticelli]

The California Historical Radio Society (CHRS) is offering the following
two receiver combos.  All proceeds will go toward the preservation,
archiving and display of radio history, both equipment and literature.

R-27/ARC-5 with homebrew power supply and Q-multiplier.  The R-27 is black
with good paint, complete (except for dyno and tuning knob), and in good
overall condition.  No corrosion or re-cap.  There has been minimal hacking
as the owner knew what he was doing and respected the unit.  For example,
the rear socket is engaged by proper mini-bananas and likewise the dyno
pins are engaged with mini-banana sockets. The drawer has the obligatory IF
gain pot installed in the middle hole but no other holes drilled. The power
supply is nicely built on a separate alum chassis.  It has a 250V
transformer for B+ and a 24V transformer for filament.  B+ is regulated by
a VR-105.  The supply has switches for AC On/Off, DC On/Off and BFO On/Off.
The Q-mult is built as a sidecar to the receiver.  It features a 12AT6, a
selectivity pot, a BFO freq var cap, AVC On/Off switch and an audio gain
pot.  The combo is untested and sold as-is.   Price is $50 plus shipping
from CA.

BC-454-B with homebrew power supply and Q-multiplier.  This is made very
similar to the R-27 setup.  The BC-454 is silver, in good overall shape,
but missing it's tube cover, dyno, tuning knob and having a replacement
bottom cover.  No corrosion or re-cap. Same use of mini-bananas, hence no
solder desecration of plugs and jacks.  The front drawer is black wrinkle
and has the single IF gain pot in the middle.  The power supply is on a
separate chassis with AC, DC, and BFO On/Off switches.  The B+ transformer
looks very similar to the R-27 but is unmarked.  Also uses a VR-105 and
24VAC.  The Q-mult is attached as a sidecar to the receiver.  It uses a
12AT7 twin triode and I do not see a selectivity control.  There is a pot
for audio gain and a var cap for BFO adjustment as with the R-27.  The
combo is untested and sold as-is.  Price is $45 plus shipping from CA.

I have photos of the inside and out available for serious buyers.

Please give these a good home and help out CHRS in the process.
