The following is a current list of some of Uncle Joe's (VA3UJ) equipment.|
TO ARRANGE A PURCHASE, PICKUP or SHIPPING CONTACT Rick: firstname.lastname@example.org
REALISTIC offers are welcome.
HOMEBREW LINEAR AMPLIFIER-built in an Apache cabinet. Bandswitched 80-10 meters. Ruggedly built of high quality components using a pair of 4-400A tubes running in triode configuration. No documentation; on-board filament and bias supplies. Looks like step-start for outboard power supply switched on and off from the amplifier. I have seen this amp running at 700W. Can not find the power supply anywhere so can not test.
PK-80 packet TNC untested but in good cosmetic condition. $10
GREENLEE CHASSIS PUNCHES-1.25 in round-$15; 2.125 in. round-$25; 1.25 in round (missing bolt) $10; 1.125" round $15; 1/2" conduit $10; 3/4" round $15
HOLE REAMER-USA made. 1.125`max diameter, good condition. $10
ESD GROUNDING WRIST STRAP-curly cord extends to 4 ft. $10
YAESU FP-107 power supply, 20A continuous, 27A surge. Tested and working. Power cable pigtail but no connector. Cosmetics about a 7.5. $65
Soft Rock Ensemble RXTX SDR transceiver radio kit. Joe built three of these plus a number of receivers. This kit looks to be complete with board and all parts in a bag. Full manual plus lots of additional info in a big binder available to the seller. This kit currently sells for $95 USD. Asking $85 CDN.
VINTAGE MICROPHONE-from the 1940s, this Turner model 33X. Very good cosmetic condition; tested on scope and produces good audio wave form. Comes with cable and 1/4" plug. $80 OBO
SDR RECEIVER-SoftRock RX Ensemble II tested on 40M and in good working condition. Built on a sheet of plexiglass with a RX preamp installed. Full manual;software downloadable at KB9YIG. $45
DOORKNOB CAPS-Brand new Russian caps from Dr Alex, UR4LL and listed on his web page in $$$US plus shipping. I ordered these for Uncle Joe in November 2015 along with my order...he never got the chance to use them.
Qty 4 470 pf @ 16KV-$5 each
Qty 4 1000 pf @ 12KV-$7 each
HEATHKIT SB-230 LINEAR AMP-This amp has been modified to take a single Russian GI-7B tube. Amp keying has been modified from the stock 110V to 12V @ 70 ma. A countdown timer has been installed to allow filament warmup before application of B+. Status lamp system has been removed; a new changeover relay has been installed; two small 12V power supplies have been added for relay control. A cooling fan has been added to the rear panel. RF components are stock but additional loading capacitance is required on both 80 and 40 because of the difference in tube characteristics from the stock 8873.
The amp has been tested on all bands and currently produces about 450W PEP on all bands. Currently, idle plate current is fixed at about 10 ma and is too low...this can be fixed by changing out the zener. Changing idle current and adding load capacitance on 80 and 40 will raise power output to well over 500W.
This amp is a "work in progress"-Joe was unable to fully complete the rework before he passed. Selling with spare GI7-B tube (supposed to be tested good). Schematic and "manual" (such as it is) are both available on the web.
Asking $350 OBO.
Power supply board complete from SB-200 linear amplifier. Caps and diodes test good. Little sign of heating of the board. Meter resistor has been replaced as have balancing resistors across the caps. In very good condition. $20
Heathkit SB-200 power transformer removed from working amplifier (above). Good condition. $45
