I still mourn the death of Heathkit, like a long lost friend. After that fix the distortion went down to under 0.02%.

The only repair I've had to do is replace a resistor in the AG-9A audio generator which had too low a wattage rating causing value shift and 4% harmonic distortion. I'm impressed that all my Heathkit tube equipment from the 50s and 60s still functions very well indeed. If you look at the schematic, there are very few caps in the circuit. Those wax covered paper tubes are hiding the reistor values underneath them. In the 60s I replaced the 1.5V D cell for the ohms function with a power supply kit sold for that function and the zero and ohms pots with the vernier (planetary ball) pots availble from Heath which made setting zero and ohms far less touchy. If I hook up the VCR through the antenna connector, It works fine. I cannot get a picture on the Antenna Connection.

The Heathkit has a db scale and no separate scale for the 1.5V range. I have an RCA TV model L40HD33DYX12, serial I214CU0FS. It's a close cousin to the RCA who had all the standard tube circuits in their tube manuals. When im finished I’ll polish it one last time.I still have my Heathkit V7-A VTVM which I built in 1957 working. I even polished the front panel and has a chrome look to it. I think if I rub it down with a anti-static sheet it will dissipate it. I used some plastic polish on the meter face and now im stuck with a static issue that moves the needle. Good thing I have a wide assortment of 1/2watt Metal Oxide resistors. I have measured the fixed Carbon comp resistors and they seem to be out of tolerance. I don’t know if these meters were offered as a kit or not but it seems to be in bad shape. Some of the wires are 22 gauge telephone wire and some have the cloth covering or with typical rubber coating. I may have to end up rewire the whole thing since there is a mix bag of wire types and gauges that don’t seem right since this uses a high voltage. I also numbered and wrote a legend sheet out to keep track to what wire is what. Granted this does not count as in a “restore” of bringing it back to its new state but in my opinion better and safer.īefore painting it I had to drill out the rivets for the tube sockets and a few standoffs. I also painted the chassis with some Semi-gloss black high heat exhaust enamel from Duplicolor since it prevents rust and holds stronger than the rustoleum stuff. I stripped down the whole thing and wire brushed the chassis using my Drill Press with a wire wheel.
