John, I have orders for 6 PCBs - but the minimum quantity to order is 10.
I have to wait until the quantity is reached.

Hello Rudi,

would it be possible to use 22VAC transformer instead of 25VAC for the backend?

Cheers,
Marcell

Morning Rudi. Interesting build and could be my future one. What is a total Cost for an amp minus Traffos and box, on average?

 

[Rudi_Ratlos]

MarcelID, you can use 22VAC transformers. ROENDER recommends to use 25 VAC for optimal performance though.
Ivar: hard to say. I guess that 2 populated shunt and 2 populated AMP PCBs without heatsink will cost about 200€.

If you use 4ohms speaker then the lower transformer voltage is advisable.
25-0-25Vac is good.
But I would be very tempted to try 30-0-30Vac for 4ohms. There is enormous Thermal capability in the 3pair output stage.

For 8ohms only (and higher) I use 35-0-35Vac for a +-50Vdc supply. That gives me a 100W amplifier. I don't have any 4ohms speakers and never will have.

Read a bit about amp. Pretty decent in terms of feedback from builder 🙂
Shall I dig into my budget again 🙂 ? Tricky though with 2 more ongoing projects 🙂

Hi. Yes go for it ,these pcb s might never be offered again 😀

 

[MarcellD]

Rudi, please count me in for 6 AMP-PCBs and 6 Shunt-PCBs.

Thanks,
Marcell

 

[Rudi_Ratlos]

Gentlemen, this is the current order status.
I will order the PCBs next week.

Best regards - Rudi_Ratlos

 

[franzm]

Rudi, please count me in for 4 AMP-PCBs and 4 Shunt-PCBs.

 

[wineds]

Rudi, please also count me in for 4 AMP-PCBs and 4 Shunt-PCBs

 

[Rudi_Ratlos]

Franz, Paul: you are welcome!
Since I want to order the PCBs next weekend: please transfer the total price incl. PAYPAL fee to my PAYPAL - Id: RRozek@t-online.de

Is somebody of you willing and has the time to order the NJL transistors (from MOUSER, VERICAL, ...), measure and match them?

Best regards - Rudi

 

[wineds]

Thanks Rudi. Happy to help with the ordering and matching of the NJLs but I haven't done that before and I am a long way from everyone else so freight costs may be prohibitive?

I hope you are enjoying your holiday! I will try to make the payment today 🙂

 

[wineds]

Edit : Just paid Rudi. Thanks! 🙂
