I think it could be a very nice and simple to make for a novice Delta-Sigma sound with silver transformers and homemade silver resistors. This is one of the finest EF86 ever made. Come out of the boxes like new. Yes, I constructed the “zoomed” graph because the Cree datasheet curve was mostly concerned with the higher I region. Regarding the use of transformers and very small resistors a tip from Joe Rasmussen over at DIYaudio the point seems to be to force the Sabre into current output mode.

Wider range for filament voltage, and a lot more. Original Blue Yellow Box. Come out of the boxes like new.
One of the BEST? Tesla NOS tubes have been a forgotten treasure for a long time. Regarding the use of transformers and very small resistors a tip from Joe Rasmussen over at DIYaudio the point seems to be to force the Sabre into current output mode. Rhodium is in the family of “hard-metals”, same as Molybdenum, or Tungsten.
The most amazing is the constant quality of them.
D3a triode – Bartola® Valves
I also used a limited set of cathode bias resistors 26, 52, ohms and plate supply voltages – volts. Best way to bias a D3A triode connected tube? The heater in the cathode, as seen from the other side:. GU50 is extremely strong and very low distortion. They come out of the boxes with shiny pins, and clean print, like new made yesterday. It is so funny to see how the old story repeats over and over again.
So no machine made tube. For low output cartridges, it will be difficult.
Tag: D3a triode
I have an original old pricelist. Here is a radio circuit showing 82Volt Anode voltagem, and 7mA plate current. Ip is plate current in mA this also includes the screen current in triode mode.
So do the pinched glass D3As seem any different in terms of construction, parameters or sound? C3gS Valvo Order Number: They are not just a “little bit” triode like, as you may know from KT88 or EL34 in triode mode. If you want to use any material from my blog please contact me by email. Great – cannot wait to read about the D3a LCR phonostage!
Please check the Triode curves!
Brandon Doetzel June 6, at 2: Inside are individual boxed tubes. Look at the excellent data it has: Hi Josh, the construction looks the same. And yes – I’m planning on going “insane” but with directly heated tubes.
Please let me griode if you need matched pairs, we can do so with the Amplitrex AT Somewhere nice on planet dirt Joined: Sridhar Ganti December 26, at 7: S-Version with selected parameters. Good starts at 2. I recommend a MC step up transformer Thomas.
