Amplifier Tone Boards 83-14 for the Heathkit AA-100 and AA-50 stereo amplifier. Brand new replacement boards using surface mount and thru-hole mount components. Great to replace those cracked or damaged Heathkit PEC boards. Most of these 50 year old parts are completely out of spec. Listing is for a set of 2 boards. See my other listings for individual boards. Shown installed on my all new AA-100 Pre-Amplifier board. (Not included) Check my other listings for HeathKit replacement circuit boards
