JJ / Tesla ECC803s / Hi-Gain 12AX7

The new JJ/Tesla ECC803s is a hi-gain 12AX7 that has a spiral wound filament to reduce noise and hum. The construction is different from the JJ ECC83 in that the plates are more conventional, but have a special heat dissipating fin that serves to improve efficiency and gain. If you want that great JJ tone in a hi-gain package, then these are for you.

Price is for a Single Tube
