Product Description

The JJ Electronic 5751 – A lower gain ECC83 for Clean Sound !

The 5751 is a lower gain ECC83/12AX7.  So if you want to get more headroom and that clean sound then this valve is deal for replacing the first valve that takes the inputs from your instrument. So for you country players this is definitely worth putting in your  amp in the first valve position which has an ECC83/12AX7.

Amps such as the Fender Hot Rod Deluxe and the Fender De Ville have a volume control that is challenging when trying to set a lower leve volume. A slight movement of the volume control and the amp goes from a whisper to a roar. Fitting a 5751 to replace the standard 12AX7 makes the amp much more controllable.

We have fitted thes to several of these Fender amps with great success.

This valve has lower gain than a standard ECC83 or 12AX7

We test every valve we sell on our range of vintage and modern testers and you have a 120 day warranty and the choice of standard or a matched and balanced 5751

We have kits of preamp valves have a look !

"I don’t think I’m the only guitarist out there who knows his/her guitars, but very little about tube amps. I ordered a Supro valve kit (which is great), but it’s the service, help & advice I received from Stewart that was outstanding. I was going to say ‘these guys’, but it didn’t seem right, as my communication was just with him. Thank you!" - Robert G.
