post #5491 of 10831

I'm not a 596 fan either. I don't find them sounding the same as as 5U4G tubes Stavros. The 596 is very dynamic whilr the 5U4G have more body and bass, treble is not as pronounced as with the faster 596. It was nice to try and I thank Clayton for the tube, but it's been safely stored now. The RK60 is a mix of both but it's closer to the 5U4G.

 

It seems like we finally got people to try the RK60. I hope they'll like them. I personally think people just want to use rectifiers that need adapters with connectors to go on top of the tubes, just cause they look cool.

Glenn, besides the usual bunch and the RK60 and 596, is there another special tube we could try? You discovered both so maybe there's another one?

(one can hope, right?) :o

Ultra, it's the same as the 5U4GB, I don't know how close it is to the 5U4G, I haven't tried any of them.

My comments are theoretical I am only going by the construction and specs.

 

Glenn has given my a nice RK60 but I haven't tried that either.

I am not a rectifier person, I prefer simple choices when it comes to rectifiers.

 

It's good to have people who roll rectifiers I am sure there's lot of fun in it.

It sure is cheaper than rolling 300bs, and the C3G is not rollable, so...

 

Oh, did I tell I scored a huge number of NOS RCA branded mesh plate Tung Sol 6SJ7WGT? I wonder how much these go for nowadays. there's a pair on ebay for 150$ :cool:

I am running out of neat looking 5 volt rectifiers to come up with. The RK-60 is close to being a 5U4G.

Stavros is right about the 596 it is identical to a 5U4GB and probably sounds the same yet everyone hates

the 5U4GB. I think nobody likes the looks of the 5U4GB and don't use it even though it is far superior

to a 5U4G.

I really don't know I use TV damper diodes in my 300B amps.

Damper diodes have the lowest switching noise of any diode SS or tube. You cannot here switching noise

it just makes the music sound harsh.

In amps that I sell I make them take the 5 volt rectifiers because everybody wants them. In the OTL I

really made to take the 3DG4 another TV tube but wired the socket to take the 3.3 or 5 volt rectifiers.

And it really should only use the 3DG4 or GZ37 that can handle 350ma you can use a 5U4/596 but you

are cooking it

But I never recommend using the 5U4 I always say to use a GZ37 that is getting pricy.

Many TV damper diodes and the 3DG4 can be got for $1.00

How about GZ34?

For what amp? The GZ34 is a good tube though.

Why not use damper diodes?

post #5499 of 10831

Just as well people don't like the 5U4GB!!

GZ34 instead of 5U4G with C3g and 300B? I kind of love tube rolling, is damper diodes will limit me on the option of rolling?

We can do that indeed. Looks like you'll be getting an amp like min, but with the Lundahls?

 

Guys, I love the 5U4GB RCA sound, it's my fav rectifier. Ok, it looks less cool, but the sound is awesome in Glenn's amp.

post #5502 of 10831

what about regular RCA 5U4G? 

 

i think Frank I uses them in a Wa5 and says they're really good.

 

how does RCA 5U4GB compare?

post #5503 of 10831

Same thing, other shape? Bottle vs bulb. I remember recommending them to him.

We could also use 5931 tubes I reckon, I have about 20 available but haven't tried yet :rolleyes:

I have a Sylvania 5U4G that I really like.

 

 

It was great in the Decware. I need to find a twin for it t use in the Cary.
