Selling my TO3-SYMASYM
 
4 Attachment(s)
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: http://www.diyaudio.com/forums/group...3-symasym.html

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 15.000F/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

Very tempting!!

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

Are you planning to sell all 3 versions?

Rudi_Ratlos 14th September 2012 11:43 AM

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

The SYMASYM has been sold a minute ago.

Best regards - Rudi
