The following is a FULL LIST of all of Uncle Joe's (VA3UJ) equipment for sale to date.


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 NO SHIPPING at this time

HEATHKIT SB-200 AMPLIFIER-This amp has also been converted to Russian GI7-B tubes employing an external power supply (2400V @ 1A). This amp is UNTESTED by VE3NH because the HV cabling from power supply to amp does not employ industry standard wire and HV connectors. Joe did have this unit on the air before he passed and called in to ONTARS many mornings running about 800W PEP which he indicated was "loafing along". Inspection reveals that the RF deck is pretty well stock except for the tube change. This amp should be inspected prior to purchase-it will probably require either manual or automatic HV delay and some additional loading capacitance may be required. Looking for $275. Additonal GI7-B tubes are available for $25-35.

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 pickup only at this time

MIRAGE WM-2 VHF wattmeter-"sort of" works...meter reads a bit on some scales but will not adjust properly. Possible chip bad on board...adjust pots are all good. Technician special. $20

HUSTLER/NEWTRONICS HF MOBILE ANTENNA-This consists of an 8 uh coil wound on a robust form inserted into an MO-1 folding base between the 3/8 stud mounting and the rest of the mast. Very professionally done. The following Hustler resonators which attach to the top of the folding mast are included: RM-10S, RM-7, RM-20. There is also a modified resonator similar in size to the RM-7. All resonators test good continuity. Complete system $75 OBO
