Great job Rudi. I'm in for 2 boards.
Also interested in the "small kit" mentioned on post #15 and/or in output transistors for a stereo set, if available. Can you please send me cost details?

Thanks and regards
Igor

Thank you very much for your interest, gentlemen!

Since I have been asked, I will offer you as well:

1) a PSU PCB
The size of the PSU - PCB is: 125 x 85mm.

2) a Speaker Protection PCB
The size of the LSProt - PCB is: 68 x 39mm. You need one PCB per speaker.

...and ...

3) a Soft-Power-On PCB
The size of the SPO-PCB is 100 x 65mm.

I will give you further details on these PCBs later on.
All of these PCBs have supreme quality and are 100% approved.
(I prototyped the Soft-Power-On PCB but did not yet have it etched professionally.)

@Gig: I will not offer the "small kit" (consisting of TO-3s, emitter resistors, ALU-L profiles, ...), because the kit will increase the shipping costs immensely!

There is only one drawback concerning my offer (and I am a little sad about this):
Once you have listened to my TO-3 SYMASYM, you will no more visit this forum, you will no more look at my current creations, ...

"You will have found your sound."

This is the current "interested party list":

Thumbs up Woohoo!

Hello Rudi,

I was so badly hoping there would be another round...

Please put another 4 TO-3 Symasym PCBs on your list for me.

I am impressed with the effort you put up to supply us with these lovely boards!
Keep up the good work!

Sascha

Is that really you, Sascha?

Since it is raining "cats and dogs" in Hamburg, I took my time to complete the 2nd channel of my own TO-3 SYMASYM.

I drilled the ALU-L profiles for my PCB (this is how I do it- I will give you the drill-pattern as well):

and started to solder the BD139 - Tempco and the TO-3s:

Do not worry, gentlemen!

You do not have to assemble a complicated heatsink like I have done!

Your Version 2 - PCBs will have the drivers sitting on the ALU-L profile!
Have a Look at post #28! Your PCBs will be "perfect"!

But: isn't DIY beautiful? To saw, to drill, to solder, ..., and finally listen to an AMP like this, "to YOUR AMP"?

Best regards - Rudi_Ratlos

Hello Rudi,

If you mean Sascha from the german AAA-Forum I have to disappoint you.

I have thought about buying all TO-92 transistors (plus a lot extra for matching) off digikey since they have all the needed small signal transistors (including MPSA18) from ON-semi in stock.
Its quite a bit dearer of course compared to the parts that you and I guess most of our german fellows have bought from Reichelt.

But would the extra cost be worth going for ONs?

Regards,
(The other) Sascha

Hello Rudi,

please put me on your list for 2 SYMASYM Boards and 2 PSU PCBs.

Will they also run from 2x18V AC? Have some 300VA trafos lying around...

best regards, Daniel
