At a time when AF power transistors were replacing valves datashheet no VHF transistors were available the ECC86 was designed to operate directly from vehicle battery supplies for car radio applications alongside transistors. Vacuum Tube Rolling Guide. I know it is still there in the background and that is the part that bothers me.

The AF pre-amplifier uses the EF98 connected as a tetrode a and g3 connected together which is transformer coupled to an OC30 driver stage. That is, there is not a nice clean line between the chrome splash and clear glass, and it is very uneven. My Voskhod tubes are starting to sound better, hearing some things in Pink Floyd I never heard before, weird when that happens.
But it really seems that they are as great as people say. Headphone Reviews and Discussion – Head-Fi. Found one real chrome dome frombut the other tubes I have fromand with a chrome top are not chrome domes.

If you don;t have chance to do direct audition, read other user experience who has similiar amp. Sometimes it is just impossible to get clear of until you change the tubes or try various grounds on the adapters.
Nov 12, at 6: The Philips Paladin car radio used these devices and could operate from the then common six volt vehicle supplies as well as the then newer standard of 12 Volts. In the early days of European transistors the Mullard Philips naming convention was still used.
Datasheet Type ECC86 was first introduced in Little Dot Tube Amps: This technique was used until the early s, but the ECC86 was especially problematic.
No, create an account now.
This was because the physical manufacturing tolerances made receiver alignment necessary after a valve change. Nov 13, at Only problem is that there is more hum than I like – drowned out by the music but still there. Two Germanium OA72 diodes act as demodulator. Dataeheet, try directly in your system,listen the sound is the best way.

Checked my inventory of Sylvania 6SN7 tubes. Your username or email address: On these, the chrome coating is slightly uneven but only covers the top portion of the tube. Thanks Gibosi, I thought there was some relationship but couldn’t remember what!
The electrode assemblies are wider, front to back, than more standard valves. Nov 13, at 1: The first and second IF strip has five stages: Anyhow, I am now in C3g land and exploring.
