EF860 EF800 RFT, true NOS/NIB, gold pins, STAM SA-47

Description

RFT EF860 drop in replacement for any EF800. This tube is absolutely new and in immaculate condition.

This is the EF800 version made by RFT in the 1960ies. This is a direct plug-in replacement for the Telefunken EF800 but allows for higher ratings and is more forgiving to low heater voltages like in the STAM SA47. Siemens actually sold this tube as EF800 in the European market.

The STAM SA-47 Mk1 came factory equipped with the Siemens labled EF800/860. Should you want to have an exact replacement, here we go…

Each and every tube will carefully be tested before shipping to guarantee best performance.

The tube is guaranteed to be new and unused from professional service stock!
