The weekend is here and that means it’s time to settle in, listen to some great music on the Ceasar, and enjoy some fine whiskey.

Absolutely beautiful. I have the same cans and can’t wait to hear a GOTL with them. Enjoy your whiskey and your weekend!

I had that whisky at a whisky tasting night a couple of weeks ago. Very good.

I can’t find a website to see models and pricing ?

There isn't any. You need to contact @2359glenn directly.

My kind of combo. Enjoy!

Howdy, would just like to ask what are the rectifier tube options that one can pursue for this amp?

I've seen 5CU4, GZ32/5V4G and GZ34s mentioned in various posts.

I've just gotten in line for a GOTL next year, trying to figure out what I should be on the lookout for lol.

Appreciate any guidance, thanks in advance...

Generally, you can use any rectifier that can provide at least 250 milliamps. You should know that there is considerable confusion regarding the GZ32. Even though the 5V4G is listed as an equivalent, it is not. The GZ32 can provide up to 300 milliamps while the 5V4G can provide at most 175.

Glenn typically provides a 3DG4 with the amp. In addition, 5U4GB (but not the older 5U4G), 5R4G, 5AW4, GZ33, GZ37, 53KU, 596, 1641 and U52 are commonly used. And some of the more well-heeled among us use the Western Electric 422A.

Noted, will pay attention to the tube data sheets before buying anything.

Thanks for all the info, much appreciated

I just plopped in the fuel rod for the nuclear reactor that Glenn sent with my amp.

Cool I am using the 5U8C in my old amp. That is the only rectifier that won't blow up charging two 4700uf filter caps.
Can't even use any other rectifier it has the crazy Russian socket.
Crazy using those caps but I wanted total silence was nuts at that time money no object.

Ha, yep....that is pretty crazy!
It is overkill for the EL3N amp...I like how it towers over the EL3N tubes though.

You marked the pins of the tube and the socket with red so that I could not mess up when installing ...glad you did as the tube will fit in the socket every which way.

From Deyan: "Since the 12SN7 has a dual cathode and FDD20 has one cathode for both triodes and we don't know the value of the cathode resistor if i connect the 2 12SN7 cathodes I'm basically halving it's value. So since we are in the dark ill put a switch on the thing so you can choose whichever setting suits you better. This is the only way i can guarantee proper operation. In case you want it in the switch in the up position uses both cathodes so 1/2 cathode resistor in the down position is with one resistor. You can ask Glenn if he uses one resistor in the amp or he uses 2 resistors."

What do you think @2359glenn?

The adapters look great. And now that the Canadian postal strike is over I should get my adapters in a few weeks.

I think that is great. I would say hook it to both cathode resistors. But with the switch you can pick what setting sounds best.

That’s a pretty sweet adapter Leftside. Let us know how it sounds.
