Default Mullard QQV0640A Valve & Base.

Don't know if there's any demand for these valves nowadays. They used to be pretty standard for amateur radio VHF transmitter P.A stages and for PMR radios back in the 1970s. I don't know whether this one is N.O.S or used and can't test it, but the heater is good. It comes with a PTFE B7A base which looks to be N.O.S, and the two aluminium block anode connectors. The QQV0640A is a two beam Power VHF Tetrode, with maximum 40 Watt output (20 Watts per anode). The data can be found here:

http://www.r-type.org/pdfs/qqv0640a.pdf

If it's of any use to anyone, I'd be happy with 5.00 plus 3.00 post. (Paypal or a cheque after valve safely received by buyer).

No 'hat' if anyone wants it.

I don't frequent other forums, but whoever it was will only need seven if he spots this one and buys it!
