Default SRPP schematic and frontal view of your pcbs please.

Hi,

There are several variations among SRPP circuits, so would you post your implemented schematic please?
Also a frontal view of your PCB would be very helpful, please.

Warm regards,
Ion

Default Heaters

Hi puremilk,

I try to understand how you implemented the PCB for your SRPP circuit. Unfortunately you didn't post details about your PCB (how is placed and connected each component in the circuit, the ground layout etc). I would wish to ask you details about the heaters. According to your PCB image it seems that each heater is separately regulated (LM or LDO, fixed - adjustable?).
It's possible to use 12V6 or 6V3 for the heaters, please?
What about of pin 9 of each socket, please?
What about the elevation of the heaters, please?
What about the ground of each SRPP circuit, please?
Many thanks for your kind answers.

Warm regards,
Ion

Yes,each heater is seperated and regulated,regulated circuitary is included on the PCB,please see my regulator diagram,regulation IC uses 74...series, heaters voltage depends on tube type and you dont need to do any heater pins rewire for 12A..series or 6DJ8.
It's possible to use 12V6 or 6V3 for the heaters, please?
Yes,that goes with your heaters voltage supply to the PCB 1,2.
What about of pin 9 of each socket, please?
pin 9 is empty,you dont need pin 9 for any tube type of heater runs at different voltages,it adjusts from the regulator.
What about the elevation of the heaters, please?
From 6.3 to 12.6v DC
What about the ground of each SRPP circuit, please?
Two grounds on the board,one for signal,one for high voltage supply ground.
Many thanks for your kind answers.

Warm regards,
Ion
Hi Ion,
Here I hope i had tried my best to answer all your questions possible.
Noted:buyer will get my installation manual only when i deliver the PCB for order.

Since this is clearly a commercial venture, I am moving the thread to Vendors.
