Hi Rudi,

Can I still order 2 amplifier boards (for a stereo amp)?

I still have some parts I've nothing to do with and this looks like the perfect amp for them :)

Hi radio,

you can find a description on the original page of symaysm: SymAsym5 - Project

Is your question answered with that?

Hi Rudi,

I've just made Paypal payment of Euros 35.85 for 4 boards.

Nice boards, and thanks for your great work and enthusiasm.

John

I received your payment.
Thank you, John.

There are only 3 transfers missing! I will once more try and contact them!
It would be a pity, if they missed this occasion!

Gentlemen,

I still have some very fine, exquisite TO-3 transistors, MJ15022 and MJ15023, at hand.
These transistors will work very well with the TO-3 SYMASYM!

I "LTSpiced" them, did the Fourier Analysis, and the result was impressive indeed!
Have a look at their datasheets, please!

I offer you:

2 sets (2 x 4 pairs) of MJ15022/MJ15023, 1 set needed to build a Stereo TO-3 SYMASYM, along with a spare pair each,
alltogether: 10 x TO-3 transistors, for 25€ per set.

The transistors are new, have never been used and are 100% authentic OnSemi.

If some of you wants these beauties, write me a PM please.

Best regards - Rudi_Ratlos

Rudi_Ratlos 15th September 2011 05:40 PM

The sets of MJ15022/MJ15023 are sold already.
Do not ask me anymore.

Thank you, best regards - Rudi

Would you like some more? Evette

Dear TO-3 SYMASYM friends,

the group-buy is closed definitely now.

I ordered the PCBs yesterday and am now waiting for the etching company to send me the PCBs' Gerber files for approval.

I will keep you informed.

Best regards - Rudi

P.S. If somebody of you likes to have 100% authentic TO-3 OnSemi transistors MJ15022 / MJ15023: please contact EVETTE directly.

ZTX450 is too noisy for using it in the input instead of MPSA18, right? The noise figure isn't quoted for the ZTX.
