This is a pack of two valves.
The JJ ECC83S Gold Pins Preamp valve indeed does have gold pinned connectors but overall customer feedback is that it does have better sonic qualities. Users report that it is a richer and smoother sound as compared to the standard ECC83S and other manufacturers.
It is also a low noise 12AX7/ECC83 type and is highly recommended for the front end of Hi-Fi amps
This makes it a great choice for fitting at the input of your amp in the traditional V1 position which is the position next to the inputs of the amp.
The JJ ECC83S gold Pins preamp valve is more expensive so if you want to invest you can fit this version in all the ECC83/ 12AX7 positions in your amp. A more cost effective route is to fit one in the V1 position.
In addition to factory testing we also test these valves on our range of modern and vintage test equipment as was used in the production of valves back in the 1960s.
We also offer a 120 day from receipt warranty on the product ( excludes user caused mechanical damage ) for peace of mind .
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
