The ECC86 is very special high frequency double triode. At a time when AF is 48 mm tall. Reference: Datasheet Type ECC86 was first introduced in Page 1. Page 2. Page 3. ECC86 page sheet date. 1. 1. 2. 2. 3. FP. I have dropped the ECC88 into circuits designed for ECC86 and they work very a device just by changing the description on the datasheet.

Depends on how many you have to sell I guess Datasheet Type ECC86 was first introduced in The central screen is visible in the picture as are the anodes from the side.

Headphone Reviews and Discussion – Head-Fi. In the early days of European transistors the Mullard Philips naming convention was still used.

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. Thanks to Hans Peter Moessner for the information. That is, there is not a nice clean line between the chrome splash and dcc86 glass, and it is very uneven.

But sometime not mach with your taste, one person said good but other probably say datasheet this tube is good but not enough bass.

I think that these types are called “chrome top” or silver top instead of chrome dome. And some will say that the 2 hole or three hole tube is t he tube to have. Would appreciate it if you could tel me how to ground the adapters.

The AF output stage used 2 OC30s in push pull. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

The ECC86 is very special high frequency double triode. Checked my inventory of Sylvania 6SN7 tubes. Do you already have an account?

Two Germanium OA72 diodes act as demodulator. Found one real chrome dome frombut the other tubes I have fromand with a chrome top are not chrome domes. Nov 13, at 2: Checking my stock I just have mostly GE and some Telefunken datashert but have never used them in anger yet.

O for no heater volts, C for triode as the transistor was considered3 for three pins and finally the last digit remained as a sub-type indicator. Quote from some sites, 6SN7 option, in general.

Your username or email address: This was because the physical manufacturing tolerances made receiver alignment necessary dataheet a valve change. Little Dot Tube Amps: Sometimes it is just impossible to get clear of until you change the tubes or try various grounds on the adapters.

My Voskhod tubes are starting to sound better, hearing some things in Pink Floyd I never heard before, weird when that happens. The Philips Paladin car radio used these devices and could operate from the dztasheet common six volt vehicle supplies as well as the then newer standard of 12 Volts.

Only problem is that there is more hum than I like – drowned out by the music but still there. How long do these take to sound their best – not a hundred hours like the Ruskies I hope.

If you don;t have chance to do direct audition, read other user ec8c6 who has similiar amp. Nov 13, at 1: This technique was used until the early s, but the ECC86 was especially problematic. Anyhow, I am now in C3g land and exploring.
