Hi Brian, the set has two 6F15 valves; no 6F16. I can supply one used Mazda 6F15. On the VCM163 it tests as follows, specs for a new valve in brackets Ia=6.1mA (7.0), gm=1.5mA/v (2.3). £5 inc p&p. Send me a PM if interested - you might want to wait a bit to see if anybody can supply the lot and save postage. Cheers, Jerry

Hi Jerry, thank you for info on the 6F16; I was going by the service sheet and not what valves are actually in the set.

Yes, I will hang on a bit to see if anyone has a set. I have no problem paying for the valves but it's the cost of postage that is most annoying when purchasing individual items.

Anyway, thank you for your kind offer and will be in touch. Brian

I stand corrected Brian, V2 can indeed be either 6F15 or 6F16; I hadn't looked beyond the spec on Page 1. Every day's a schoolday.... Cheers, Jerry
