I have a number of these NOS Russian valves to sell I can do two for £5 posted or four for £9. PM me if you want different numbers.

I'D like to try these if they can be used as a direct substitute to my ECC83's in my EAR834 clone.

[Lawrence001]

Personally unless you know that they can be substituted I would avoid using them as direct replacements for an ECC83. They may need two pins joining, or the heater voltage is half the usual or something like that, I forget exactly what, though they are suitable in some applications.

Unfortunately they are not a direct equivalent Andy.

Pin 9 on the ECC83 is the heater centre tap, pin 9 on the 6N2P is a shield between valve halves.

There are adapters to use this as replacements for 12AX7s.

Are these the black cap or crome top variety? Its hard to tell from the pics..

[Lawrence001]

I think using adaptors still leaves the heater voltage issue, unless connecting two pins splits the 12v into 2x6v. I didn't know about the chrome/ black top difference, they look shiny chrome to me, what's the best way to tell?

Thanks Alan for the clarification. Sorry Lawrence, GLWTS.
