Selling my TO3-SYMASYM
Gentlemen,
I want to offer you "my TO3 - SYMASYM". This has been "my demonstration SYMASYM" for the past 5 months, used to demonstrate to German DIYers, who wanted to listen to its sound and visited me. Please refer to my group-buy regarding the SYMASYM-TO3-version: TO-3 SYMASYM I offer you the following PCBs: - a small PSU (secondary is 2x12VAC, 125mA per secondary each), only one of the secondaries is used to drive the "Soft-Power-On - PCB" - the Soft-Power-On PCB, which is used to restrict the inrush current - the "big PSU - PCB" with heat-sinked MUR820 rectifying diodes and 4 x EPCOS capacitors at 15.000µF/40VDC - 2 TO3-SYMASYM PCBs having TO3-MJ21195/MJ21196 as OP-transistors - 2 Speaker protection PCBs My SYMASYM is adjusted to a quiescent current / bias of 40mV, measured across 2 emitter 0R22 resistors, meaning that about 90mA of quiescent current will flow through the TO3s. What is needed to finish this amplifier? You need a cabinet, 2 heatsinks, 1 transformer rated a 2x25VAC/300W and an attenuator (for example a dual 100K potentiometer). I will sell you the 7 populated PCBs for 150€ - shipping cost (world-wide) is included. If you any further question: please contact me via PM. I know that some of you would give their heart to have this AMP. Best regards - Rudi_Ratlos |

Patrick,
in the meanwhile I have 3 SYMASYM - amplifiers: the original one and my TO3- and TO264 - versions of the SYMASYM. It is a pity to see them gathering dust. New price is 125€, shipping included. Best regards - Rudi_Ratlos |

No!
The original SYMASYM is connected to the line-output of my PC, the TO264-SYMASYM is promised to my brother. I will sell the TO3-version only. Best regards - Rudi |
