Description

An instant upgrade or replacement for the printed electronic circuit used for tone control compensation in your Fisher tube gear. This listing is for 2 boards, there are two per stereo receiver, preamp or integrated amplifier. You will receive two with one purchase . This model PEC is specifically used in lots of Fisher gear, including the 500C, 500B, 800C, 800B, 400 receiver, X100-B, X101-C, X101-D, X202-C, Custom Electra IV Console, Philharmonic V Console and perhaps many other Fisher integrated amplifiers and consoles. The sound improvement is immediately noticeable. You will have enhanced clarity and openness. The components on this board are the same values and arrangement as appearing on the schematic, so no modifications to the original sound. Where the improvement happens is that these new components are miniature 2% tight tolerance film capacitors and 1% tight tolerance resistors. The original units used ceramic capacitor construction and resistor tolerances were much looser than 1%. Installation is easy, just snip the leads from the original part, insert the leads into the numbered holes and solder. There is also a ground plane built into the new part for additional shielding. A ground wire to the chassis ground shall be soldered into this hole I am showing in pictures, these boards installed in my 500B receiver. They are shown alongside the PEC’s they replace, as well as the receiver before the replacement. I thought the receiver sounded great previously, but installing these had woke this receiver up, every aspect that I thought sounded good in this receiver just immediately sounded better when these were installed.
