The JJ ECC81 is a low noise replacement for ECC81 and 12AT7 valves. .You can use this valve as a replacement for the 12AT7, as it is exactly the same valve. ECC81 is the UK numbering while 12AT7 is the American numbering.
Many amps use the ECC81 ( 12AT7) as the reverb driver. The output current of an ECC8 is ten times higher than your other pre-amp valves so these tend to wear faster than the ECC83’s ( 12AX7’s) in your amp. It is a good idea to change the reverb driver valve when the reverb starts to get weaker and muddier and the rest of the amp sounds good.
We test each JJ ECC81 Preamp valve on our testers so that you are assured of receiving a quality product, We do matching on our Avo Mk2 tester which is recognised as the best family of testers in the market.

Note: Valves use high voltages and these voltages are dangerous. The amp can still retain these high voltages for some time even after being switched off. If you are not sure of fitting them , please seek the services of qualified personnel
