Yes the C3g have a 6.3V heater

post #11387 of 14390

Yes, I know that C3g has a 6.3 heater, but... is the C3g tied to the 6/12/25 switch? Or does it bypass this switch and connected directly to a 6.3V voltage source?

The C3g is tied to only 6.3 volts not to the SN7 switch so the switch can be left in any position when using C3gs.

Thanks! :)

 

I was just short of positive you designed the C3g circuit to bypass the SN7 switch, but again, I wanted to be sure....

I need to set it up soon.

Steven I know I am very very bad for not doing it sooner.............sorry

That's ok Stavros...I hope you've recovered from your weekend feasting!

 

I have been acquiring a heavy position in GRETA's "secret" output tubes.

 

If these tubes become the Next Big Thing, we could make enough money to buy a new DJ rig for the Beach Bar!


Steven it is a crazy circuit using diode bias or should I say rectifier tubes as cathode resistors.

And the rectifier tubes are built into the output tubes. No bypass capacitors.

Crazy Idea maybe sounds like crap can't tell anymore ???

Hi Glenn...was NY great? What did you eat?

GRETA is interesting. I never heard of using part of the output tube as the rectifier..very cool.

Let's see what Stavros thinks compared to your more conventional designs...I'm sure it's not crap!

 

Nathan...GRETA is no joke. It is an attempt to build a cheap and cheerful amp out of leftover parts that Glenn can't use after upgrading the OTL to a larger chassis and transformers. It has been in the works for over a year.

I spent a wonderful evening with parbaked and his family eating great Italian food, drinking good wine, and listening to the smooth sounds of Sheryl Crow on his fabulous tube amp. Hey parbaked -- what's the make and model of that new tube amp of yours?

 

Anyway, about halfway through dinner I said "I need another Glenn Amp!" and then quietly asked for another glass of wine.

 

Steven! Thanks for dinner!

Hi Clayton

The new toy is a custom Tektron 45 amp by Attillio Caccamo, who's also a friend of Stavros.

I don't remember any Sheryl Crow but then again I just noticed my vodka is all gone too...

Thanks George. I hope you are well!

 

I only bought it because Stavros has some and I am trying to be like him!

 

The Tektron drives a pair of 1989 Royd Audio Eden monitors from Wales.

They're only 90 db efficient but a very easy load. The 45 drives them well enough, surprisingly.

The amp has an active pre-amp section (1/2 the 6SN7 input tube provides pre-amp gain) which helps.

The source is an iPod > HRT iStreamer Transport/DAC...very simple and wifey approved...

Clayton took this pic the other night before we got too tipsy...

The Royds are designed to be close to the back wall which probably boosts the in-room efficiency.

Completely ignored the speaker with that beautiful background.   Its like one of those 70" HD 4K display rich people use as a canvas or backdrop.  But yours better because is the real thing.

 

What a coincidence, my first British speaker arrived today.  A pair of Jordan Watts MK2 drivers.  Hope their as good as my Coral Betas.  Clayton has to be one of the luckiest person been treated to good food and wonderfull music.
