Rudi, my current project is: I have sent a dozen of my "Lightspeed Attenuator" - PCBs along with the needed components to German DIYers last week, and I am now waiting for their feedback.
This PCB does not only include George Stantscheff's "Lightspeed Attenuator", it includes source selection, mute and standby function,
temperature sensors, volume display, ..., everything being displayed on a 16x2 chars LCD-display and - of course: every function can be
controlled/accessed by a remote infrared control unit.
The heart of the PCB is a PIC µProcessor.
Give me your EMail address (per PM) please - and I will tell you more.
Best regards - Rudi_Ratlos
P.S. I have mixed up the current dates.
I will close this round-of-groupbuy the day after tomorrow, on Saturday 7th.

Gentlemen, I have been told that the TO3-SYMASYM - PCBs will be etched on April, 23rd. I will then have them on April 27th
and will send them to you ASAP.
This is where I stored the BoM of one SYMASYM - PCB:
Warenkorb übernehmen - Elektronik und Technik bei reichelt elektronik günstig bestellen
You can choose the English language as well.
The BoM does not include:
- 4 emitter resistors 0R22, 5W, grid-size: about 9.5mm
- the TO3 - transistors MJ21195G / MJ21196G (2 pairs of each are needed per PCB)
- the DC blocking capacitor C1, recommended value: 10µF, max. grid-size: 27.5mm
- the input pair of transistors (f.e. 2SK170, MPSA18, 2N5551, ...)
Best regards - Rudi_Ratlos

The TO3-SYMASYM PCBs have arrived in Germany but are delayed by the German tax authorities.
The reason why: the Chinese etching company has forgotten (?) to include the bill.
Have some patience please; I try and settle this issue ASAP.
Best regards - Rudi_Ratlos
P.S.: An issue like this makes a future group-buy "complicated", since it may eventually mess up all of my price-calculations.

Hi Rudi,
No problem, if there is something more to pay for the unexpected taxes, I will pay you. Say it ! I have had this sad experience recently with a buy that I did in China that was with free delivery : here in Belgium, they did tax (heavily ) the item and the free delivery when it arrived ...
Thank you for what you are doing !
Best regards

AdeS: find attached the schematics underlying the PCB.
Joe: thank you for your kind words. I have settled the issue with the help of the Chinese etching company.
Thanks to them my price-calculations are still on the right side.

The PCBs and transistors did arrive today, thanks.
Now waiting for the components ordered from Schuro ( Elektronische Bauteile für Produktion, Labor, Audio-Tuning )
