    Default wanted tube adapter

    Looking for 3x adapter to take a ecc83 fitting to a 6n2p fitting tube as a friend of mine has a load of 6n2p tube that I can try out .

    The adapters are likely to cost more than the tubes. If the heater circuit is 6.3V its an easy soldering job to reconfigure the socket wiring (disconnect bridge from pin 4 to 5 (but leave the wire attached to whichever pin - 4 or 5 that it arrives at) , disconnect wire from pin 9 and reconnect it to 4 or 5 - whichever does not now have a wire attached.

    You can install a simple switch to achieve this to allow fairly rapid swapping.

    If the heater is 12.6V the Russian valves can't be used.

    I think that James is right. I understand that the Russian valves you want to use are part of the ECC88 family and therefore work on different voltage.
    I would not risk it as there are myriad 83/family valves around for you to play with. Many at cheap prices
