Default Shengyi 6AQ5

Hi.
This little amp just turned up. It has 4 x 6AQ5 in the output, BUT these are B9A pinned valves, and 6AQ5's are 7pin valves, so what is going on?
Anyone ran into one of these?
Henry

Probably 6P1, which are electrically similar to 6AQ5 or 6V6. There are Russian and Chinese versions - but no US or European equivalents with same pin-out.

Hi Tom, thanks for the reply, it does also say 6P1 on the chassis. Is this a 9 pin version of 6AQ5?
But why do they also write 6AQ5 when clearly it won't fit?
Are the 6P1's easy to get or will I modify this thing to run something like 6BW6?

Just type 6p1p-ev into ebay search and pick your vendor ...

Hi Dovla, many thanks , there's loads of them there.
Feel sorry for anybody looking for a 'real' 6BQ5 who orders these only to find they're 9 pin and not 7 as expected!

Could the JJ EL844 work? They have 9 watts dissipation and are 9 pin. More $ though!

euro-EL844

Thanks, I have since ordered some Russian 6P1P-ev thanks to Dovla's suggestion.
If I were to rework for different valves I would probably go for the 6BW6's as they are electrically closer to 6AQ5 whilst having similar dissipation to EL84's. (12 Watts)
