Gracies company. Thank you.
Bona nit. Good night.

Hi,
@Merlin el Mago:
Should you go through with the E2833CC mod know that these are as close to the famous TFK ECC803S as you can get.
Less distortion, lower noise, no microphony I can remember, frame grid construction and so on. But like most low distortion valves, not to everyone's liking.
Cheers,
Hi Frank,
I bought several years ago to Erno Borbely & paid a lot of money for each tube. The 6n2p-ev are sounding glorius and if memory don't falls Itch was a little bit complicated the heaters connections.

Hi,
Sure, if I were asked to design a phono preamp today I'd go for the 6N2P-Ev too.
I currently use it to drive a pair of 2A3s in an amp.
Back in the early nineties I used E283CCs as error amps in voltage regs and ECC808s, C3As and E80CCs in an MC/MM phono preamp too.
Gone are the days....
Just saying these E283CCs are not just your regular run off the mill valve, they're masterpieces of technology.
Cherish them ,

It nice in the small suitcase. Do they sell that "Duo Vac" front plate that screws in the suitcase separately?
Alain ask for DuoVac ( tester ready to use in flight-case) is 380 euros + 25 euros shipping.
Attached french manual.

Salas before changing for E283CC I want to check in the real schematic if the E283CC tubes are good, attached schematic.
TIA

I don't have model for that tube Felipe but it should be biasing fairly normally there because 6N2, 12AX7, E283CC are very near electrically.
I measured E283CC cathodes pins 1 & 6 to center tap heater pin 7 and is open circuit so looks good, also I measured heaters 4 to 5 and measures both tubes 3 ohm, is right? I ask because I have other 12AX7 brands:
JJ 10R5 I have only 1 tube
Groove tubes 9R5-10R
Sovtek 17-18R
6N2P-EV 7R-8R rocket logo
Sovtek HQ 32R-34R
RSD 12R5-13R5

Yes you can. 285V at the top anode, 180V at the bottom anode, 56V across the 82K. All those are rough estimates.
Thanks Salas.
What do you think about the heaters low ohmic value of the Siemens E283CC?
