Ne ho altre a disposizione
For sale a pair of ECC83 valves branded BELVU (MAZDA) but produced by TELEFUNKEN as can be seen from the diamond between the pins.
New, tested and matched by TRIPLETT valve testers.
If you search online you will find several references of valves marked BELVU or MAZDA but produced by TELEFUNKEN.
For the TRIPLETT transconductance valve tester one valve is good at 0.8 Gm and new at 1.2 Gm.
Excellent opportunity to take home,some precious Telefunken ECC83 at an affordable price ... given the Tfk logo lack on the glass .....
I have more pieces.
