Hi folks,
I listed this abt 3 wks ago, not a lot of interest. Any now at a
reduced price? $90 vs $125 b4
===============
I spent many hours resurrecting this "dead on arrival" TR-3 for a
fellow who then ran into finance shortcomings. He said to sell it.
It does not have a power supply. It's working reasonably well.
It gets approx. 200w out on 3.8, 7.25, 14.25 mc, 100+ on 21.25,
approx. 90 on 28.3. Receives well. I've demo'd it on 3.8.
Chassis is fairly clean, it's bright plated, not copper like later
rigs. Case could use a repaint.
The following is a quick summary of what was done. TR-3 s/n 60001
1. AC switch is bad, replacements are very hard to find. It’s “ON”, so
use a “power strip”
2. Replaced final cathode resistors with 15 ohm 1-watters, screen res.
with 68 ohm 1-watters, all were out of spec. Plate dropping res. for
the driver was high, 695 vs 470, now repl with a 3-watter.
3. C-135, -145, electrolytics, all had high ESR. Replaced with discrete
components under the chassis, disconnected the original cans.
4. C-129, at the 9mc osc., broken. Replaced with a similar one, mounted
above chassis (not “proper” but serves the purpose).
5. Re-calibrated the plate current meter, it was indicating about 2/3
of actual.
6. Someone had modified the neutralization ckt to make it close to what
is used in later TR-4’s, but didn’t do one thing properly. Now have it
working reasonably well. S-meter has quit to stay, coil is open.
Neutralization is OK on low bands, poor on 15 & 10 meters, I advise not
using those bands, or it can be adjusted to use those bands and not the
lower ones. New finals might be OK.
I will ship at actual Fedex cost, plus $5 for packing and my trip
to the terminal. Pers. ck OK with short waiting period, USPS or bank
M.O. no wait, if PayPal, add $5 to cover fees.
IIRC about 25 lbs, from zip 28560, you can ck Fedex.com for est.
