EF 86

EF86 is often found in ancient Radio (vintage tube radio),

is easy to find from the tube the other (except modern tube).

Most assemblers are used for Preamp tube amps and the input of a tube amp.

Just take advantage of Used Goods For Ampli Tube
Transformer former Philips Radio

Own use aluminum chassis bending 1.2 mm
Rectifier 6u5 russia
all still in good condition ...
for starters sound quite satisfying .... cost is quite cheap

6F6 RCA

Power Pentode
Octal Base
Uf=6,3V
If=0,7A

6F6, KT63 Power Pentode. Octal base version of type 42. Moderate power output rating—9 watts max. (single-ended Class A circuit); 11 watts max. (push-pull Class A circuit); 19 watts max. (push-pull Class AB₂ circuit). Available in metal (numbered "6F6"), shouldered glass ("6F6-G"), and cylindrical glass ("6F6-GT"). Sometimes used as a transformer-coupled audio driver for types 6L6-GC and 807 when those tubes were used in Class AB₂ or Class B amplifiers. Also used as a Class C oscillator/amplifier in transmitters.

6L6, EL37 High-powered beam tetrode. There are several variations. Except for types 6L6-GC and 6L6-GX, all have the same maximum output ratings—11.5 watts (single-ended Class A circuit); 14.5 watts (push-pull Class A circuit); 34 watts (push-pull Class AB₁; 60 watts (push-pull Class AB₂ circuit). Types 6L6 and 25L6 were introduced in 1935 as the first beam tetrodes. Both types were branded with the L6 ending to signify their (then) uniqueness among audio output tubes. However, this is the only similarity between the two tubes. (Type 6W6-GT is the 6.3 volt heater version of types 25L6-GT and 50L6-GT.)

6L6 (metal envelope) and 6L6-G (shouldered glass envelope) were used in pre-World War II radios and Public Address amplifiers.
6L6-GA Post-war version of type 6L6-G, in smaller ST-14 shape.
6L6-GB Post-war improved version in a cylindrical glass envelope. Similar to type 5881.
6L6-WGB "Industrial" version of type 6L6-GB.
6L6-GC Final and highest-powered audio version of the tube. Max. outputs—32 watts (single-ended Class A circuit); 17.5 watts (push-pull Class A circuit); 55 watts (push-pull Class AB₁ circuit); 60 watts (push-pull Class AB₂ circuit)
6L6-GX Class C oscillator/amplifier used in transmitters. Max. output—30 watts. (All versions may be used as a Class C oscillator/amplifier, but this version is specifically designed for this purpose, has a special ceramic base.)
