Having dealt with RS for more years than I care to remember, I never realised they stocked valves! they are branded as their RS Pro range but are Chinese and they offer most common guitar valves at reasonable prices. As you would imagine the datasheets are excellent including characteristic curves. I have no idea what they sound like but have ordered a few to try. The 12AX7s will be particularly useful as cathode followers, the heater with respect to cathode is 180 volts, very useful.

Seriously: If you value it, take/fetch it yourself
The matching of the EL34s is, ahem, questionable.
The EL34s are the corrected version of the Shuguang EL34B and is a good valve.
The 12AX7s are OK, but I would be wary of the other offerings.
RS free delivery sometimes makes me feel guilty. Been a few times I have been disorganised and made several tiny purchases on consecutive days - all delivered next day for free - reckon the postage must have cost more than the items.
Tell me, am I on the right forum?
Bit moot? Guy in BangyBang studios Miami says he has a stock of FIVE MILLION NOS audio valves and is soon going to put them on the market!
