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?

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 #5513 of 10319

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 #5514 of 10319

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.

I have a pair, will give it a try.

Based on Glenn's comments it seems like rectifiers don't have their own sound but instead affect the sound of the other tiubes. If so, they should sound differently in different circuits.

I've been giving away my 596 tubes. I don't use them much anymore. But they do look cool. I also like the sound and look of the GZ37 but since I am usually listening to music and not my amp, I prefer the old standby 5U4GB like the Tung-Sol.

 

Ultra-, keep the 596 and sell it in 20 years and use the profits to finance your future child's college education ;)

Might need more 596s for that C. If not it'll be your fault he turned out a bum. I kid. ;-)
