Vintage Heathkit W-5M tube amp pair Williamson circuit
Wednesday, October 23rd, 2019
One pair of Heathkit W-5M in working condition. The testing performed was the bare minimum to confirm whether working or non-working and lasted less than a few minutes. I put a pair of 5881 tubes into each and ramped up line voltage on a variac. The results of that brief test are below. Amp 1: played music at 80V line voltage and above. At 80V it drew. 5A of line current. At 90V it drew an amp of line current. No further testing was done. Amp 2: played music at 80V line voltage and above. At 100V it drew. At 120V it drew. 75 amp of line current. No output tubes are included with this listing. Both amps have the tubes shown in the photos. These are a good candidate for a restoration this winter. The tests show that some parts are out of spec but that all of the iron is performing as expected. Both have the more desirable Peerless 16309 nickel core output transformers. Plenty of information about these amps is available online and repairs parts are readily available from a variety of sources. These are offered in as-is, as-pictured condition for parts, repair or restoration. The item “Vintage Heathkit W-5M tube amp pair Williamson circuit” is in sale since Sunday, October 13, 2019.
