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.

Checked my inventory of Sylvania 6SN7 tubes. Anyhow, I am now in C3g land and exploring. 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.

The AF pre-amplifier uses the EF98 connected as a tetrode a and g3 connected ddatasheet which is transformer coupled to an OC30 driver stage.


ECC86 Datasheet

Datasheet Type ECC86 was first introduced in Vacuum Tube Rolling Guide. Post of Nov 13, at 5: Nov 13, at 1: 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.

Something tells me that many sellers on Ebay will call the chrome tops chrome domes as well. At a time when AF power transistors were replacing valves but no VHF transistors were available the ECC86 was designed to operate directly from vehicle battery supplies for car radio applications alongside transistors. Yes, my password is: Nov 13, at 9: Two Germanium OA72 diodes act as demodulator. Checking my stock I just have mostly GE and some Telefunken s but have never used them in anger yet.

Thanks to Hans Peter Moessner for the information. In the early days of European transistors the Mullard Philips naming convention was still used. The central screen is visible in the picture as are the anodes from the side.

Little Dot Tube Amps: They sound very good, kind of on steroids – they have more of everything. My Voskhod tubes are starting to sound better, hearing some things in Pink Floyd I never heard before, weird when that happens. You must log in or sign datasheeg to reply here.

The electrode assemblies are wider, front to back, than more standard valves. This was because the physical manufacturing tolerances made receiver alignment necessary after a valve change.

Nov 12, at 6: Sometimes it is just impossible to get clear of until you change the tubes or try various darasheet on the adapters. If you don;t have chance to do direct audition, read other user experience who has similiar amp. Only problem is that there is more hum than I like – drowned out by the music but still there.

But sometime not mach with your taste, one person said good but other probably say ;well this tube is good but not enough bass. Quote from some sites, 6SN7 option, in general.

So, try directly in your datasheeet the sound is the best way. The ECC86 is very special high frequency double triode. No, create an account now. I know it is still there in the background and that is the part that bothers me. This technique was used until the early s, daatsheet the ECC86 was especially problematic. The AF output stage used 2 OC30s in push pull. Depends on how many you have to sell I guess I think that these types are called “chrome top” or silver top instead of chrome dome.
