1960's Harmony H415 2x12 combo amp. 2 channels and tremolo. Purchased from Brad the Guitologist. Brad did some maintenance and added the 3-prong power cord
A full maintenance was done last year by Terry Dayton of D-Lab Electronics. The second channel has been modified to attenuate the output allowing for reduced volume or plugging in an mp3 player.
The speakers have been replaced with a pair of Weber 12A125H (4 ohm, 30 watt) speakers. The amp has been modified to accept these speakers instead of the 8 ohm noted on the schematic.
You can watch the video of the maintenance and upgrades on the D-Lab YouTube channel.
This amp sounds amazing but I don't use it like I thought I would.
