a very nice, honest gentleman to deal with - packs well and ships

   Three of the items are kinda off-topic, but wothell -  it's only Text!

FOR SALE

Tektronix 181 Marker Generator original manual in good shape: $7 PPD

General Radio 740B capacity bridge. Typical older (black) GR bridge with 
tilt legs on back of case for convenient angle on the bench. Uses 6E5 eye 
tube for balance indicator. Was supposed to have a lid but I don't have 
one. The little 2-prong recessed male line connector has been removed and 
replaced with a captive line cord. Otherwise, I think this is all 
original. The front panel has several inventory tags on it and a rough 
spot where I assume a calibration tag was. I think the 6E5 eye tube 
originally had a hood on it, but that is missing here. Inside, the unit is 
like new with typical GR museum-quality construction practices. Untested. 
This uses a 6X5 rectifier and an aluminum can electrolytic filter. I was 
reluctant to plug this in without taking the time to reform the cap. But 
that is just about the only possible suspect component. So I expect that 
this either works as-is or can be brought back by replacing one cap. 
As-is. $35

Another General Radio 740B capacity bridge. This one seems to be older 
than the one above. It is not in as good condition either. The knob style 
is different and I believe that one knob is wrong. It has the tilt legs on 
back of case for convenient angle on the bench but no lid on this one 
either. Uses 6E5 eye tube for balance indicator. The little 2-prong 
recessed male line connector is intact on this one. The front panel has 
some tag mess on it and some oxidation damage. This ain't no beauty queen. 
The 6E5 eye tube hood is present but has several dings in it. Inside, the 
unit is like new. This uses the same 6X5 rectifier/electrolytic filter cap 
setup and I have not plugged it in. I do think that this either works 
as-is or can be brought back by replacing one cap. Untested. As-is. $15

Frequency Shift Converter CV-116B/URR s/n 493 made by Crosley Div Avco 
Mfg. Corp. under order number 2131G-PH-56. This is a rackmount, 2-channel 
RTTY terminal unit that uses about 8 inches of rack space. It has handles 
on the ends that look a lot like the ones on the R390A, except smaller. 
The knobs and meters do not match the R390A. The unit uses a whopping 43 
tubes and must weigh close to 50 pounds. It has BNC connectors for inputs 
and outputs. The power connector sockets are some Amphenol-type 4-pin 
military and I do not have the matching connectors. I know nothing about 
this unit and have never powered it up. It appears to be entirely original 
and somebody was using it as a TU because it has some Dymo labels on the 
front panel that suggest ham usage. Untested. As-is. $39

RITY Adaptor Model TT-100. This is a ham RTTY TU in a small, black painted 
desktop cabinet with white lettering. The only controls are On/Off and a 
3-position switch labeled receive/Transmit/Local. Tubes used are 6AS11, 
6AG11 and 0B2. I have had this for years and have never been able to find 
out anything about it. I have so many TUs that this is just the odd man 
out. Good condition. $15

Thanks for looking.
