Copicat without a 6BR8???

[Bernardduur]

I recently got a Copicat in that lacks a 6BR8; have trouble dating it because of that. Nowhere on the internet it is named and all schematics are wrong. The PCB is very specific NOT designed for the 6BR8 because of the pin layout.

Anyone got the correct schematic? My unit lack some filter resistors / caps and it lacks some connections. Second, which tube should be used for the 6BR8? In the unit something is scribbled as ECC82 but yet, I don't know.

Lucky for you someone sribbled.
The ECC82 crosses to a 12AU7.
This tube has a very low amplification factor when compared to a 12AX7 or a 12AT7.

Tnx!

I just don't know if the scribbled bit is true or just someone trying

On this page another version of the tripple ECC83 Copicat........ So, it is a tripple ECC83

Now only the values!
