Title: C30 Rectifier - 1x GZ34 or 2x 5V4
Post by: archtop on November 07, 2007, 10:32:30 AM
Which do you prefer and why?

I prefer 2x 5V4. Why? It's smoother and sound better to my ears. The GZ34 sound harsher and great when playing loud. I did not manage to push the volume pass 10 o'clock in my apartment yet and I love the sound without the master volume. Try it and decide for yourself. It's definately 2x 5V4 for me.

+1 on two 5V4 (GZ32) rectifiers. The "CUT" control works better all the way, with the master volume bypassed.

can you use two gz34s for less sag?

Interesting. I have never tried that. I wonder if it is pointless? Does it change the sound...
Ask Nik, please.

I think that your amp will see to much voltage.

I got to hear my DC30 for the first time yesterday. My friend had just finished making it for me, as well as an AC30. It was an interesting comparison. While they sound related, they are definately different.

On the rectifier, I tried both the GZ34 and the 2x 5V4's. Both sounded good. 2x 5V4's seemed to make the amp brighter with more headroom. I was testing the amp at all volumes, and cranked (ditorted, no master volume) I think it had more definition, or note separation with 5V4's, and was perhaps a little blurrier sounding with the GZ34. These are just initial observations.

Overall, I prefer the AC30 for pushed, and really dirty sounds, and the DC30 has a more HiFi clean sounds.

For those interested, the DC30 build uses TDS transformers, and doesn't have the bright caps connected at the moment.

Can you please explain? A somewhat graphical explanation with my eyes on  the layout.

BTW, does the TDS transformers have end bells?

Kind regards, Tonebuddy

yep, 2x5V4 has made it sound better.  It's subtle but hard to miss...much smoother and distortion sounds better now.

We do have 5V4 rectos as an option actually.

Not many ppl ask for them, so...

Thanks!

Does this change of rectifyng type requieres any adittional mod to the amp? Or is it just turn off/change them/turn on?

would this Groove Tubes do the same job?

Thanks in advance, I'm really tempted to do this mod, as I have read from your experience. I barely tweak my amp, I love just like it is, but now you guys tempted me!
