#1 Wanted quite urgently: 2 (or more) 12SN7-GTA's

Completed my 300B builds and they are sounding superb, unfortunately one of the two 12SN7's I have is a bit crackly (I know it's the valve because I've tried swapping it from one amp to the other and the problem follows the valve). i only bought two, because I'm an idiot.
They need to be the GTA designation because they are being run at quite high plate dissipation.
If you have any good 6V6-GT's also, that would be good to know - I think I have the same issue on one of the Raytheon 6V6's. EDIT - I've just ordered a set of three spare Raytheon 6V6's from the same source, so I should be good on those.
Will also be tracking eBay. Thanks!
