JBL 250ti - Charge Coupled Crossover project with all new Jantzen Cross Caps, Superes Resistors and Air Core inductors. Turned out spectacular and does sound noticeably better than the original.
⭐️⭐️A sight to behold, the Technics RS-1700 Auto Reverse!⭐️⭐️
This one was not recording in the R channel, had a nasty squeal during FF/REW, and reels that wouldn't stop spinning after the tape ran out: both relay's were found to have corroded contacts, due to lack of modern replacement, contacts were cleaned. Then it just needed a drop of oil on the timing belt pulley, an adjustment of tension arm micro-switches, and a good tape path cleaning. Sounds excellent now 👍👍👍

Crown PSA-2 Full Restoration - this one got all the bells and whistles! New WBT binding posts mounted in custom 3D printed inserts, new Cardas GFRA RCA jacks, replaced all signal cables with Cardas Crosslink 1L Litz wire, replaced all speaker wire with Cardas 4x13awg Crosslink 1S, installed Furutech FI-06 IEC inlet, installed new fan from AE Techron, completely recapped with a mix of Nichicon UFW/UKG and Vishay audio grade caps, new KEMET 10,000uf/100V main filter caps mounted in custom 3D printed housing, new 25k volume pots, new Laird thermal insulators on all output devices, new relays mounted remotely on separate PCB, new fan speed control resistors all body panels repainted by autobody shop, and new 3D printed side panel inserts to replace rack handles (with Crown logo).
After offset/bias adjustments and 120 hour burn in, this one is pushing 244 watts at 8 ohms, both channels driven. Love the way this Crown is engineered, it was a dream to work on, all the boards come out nicely making for easy work. Extremely impressed by the PSA-2!
