Advice on ECC83 valves

I wasn't sure where to post this so apologies if it's in the wrong place.
I don't know much about what's available, brands or prices etc..
I'm in the UK and Amazon are selling a trio of JJ ecc83 valves for £50 ($64 ish for our American friends).
Is this about the best I can get for fifty quid and no more!
It's a trio I need btw, and I'll be looking at replacing the rest of the valves in the amp at a later date.
PP EL84 amp btw.

By NOS from someone in the UK who does proper testing or EBay, take your time and find those good deals on a matched trio (only if necessary). If you are patient, you can find very good deals. Again, take your time. I buy lots of very good tubes on eBay by waiting for the right deal. Sort your tube search by location.

Someone will come in this thread and flame me but I stand by eBay for NOS tubes if you do some research: I’ve had really good purchases from all over the world via the net and eBay.

Learn something about testing and then you will understand what vendors are offering.

Fortunately, in the US we have a few very good large and small NOS vendors who are quite affordable. You will have those in the UK as well. Seek them out and and the same time don’t be afraid of buying from abroad.

Cheers,

Greg

Hi.
Unfortunately less than decent experiences with JJ tubes.
The sample quality is very varied.
Sometimes good, and many times noisy, distortive, etc.

Try to find a reputable seller, the best ECCxx I've found were the NOS Tungsram from Europe.
Excellent electrical parameters and superb sound.

you can still find them.
 
2 of the 3 12AX7's flare up on power up.
I'm not necessarily concerned about the flare, but I am concerned that only 2 of the 3 do it...
That's a classic Mullard characteristic. The cold cathode glows real bright for a second on start-up. Nothing to be concerned about. Unless they get noisy, I would just leave them alone.

No idea who "CVC Chelmer" is, most likely just a rebrander.
