Great way to start your Saturday morning.

What is that nice rectifier you are using?

I believe it is a Loewe Radio AZ12.

Just as Ken says.

Does anyone with the GOTL have a Western Electric 422A rectifier,and if so is it really that much better than say,for example a Mullard GZ32 to warrant the price difference?

Go with the WE 422A.

This is the lowest price for a 422A: https://www.ebay.com/itm/173369443512?rmvSB=true

The WE422A blows the GZ32 away the best sounding rectifier I ever heard!!
That WE422A for $61.38 is not a 422A it is just a 5U4 the WE422A is indirect heated and has dimples on the plates like the 421A.
Here is a real one but a crazy price.

Im guessing the link you shared has to be somewhat different in sound vs. the WE 422a that goes for $500.00?

I already have the GZ32 and am enjoying it very much. More of a curiosity mainly piqued by reading DubStep girl's rectifier thread.

OK,so is the difference in SQ worth the price tag?

 

[gibosi]

There is no guarantee that it will be worth $500 to YOU. And if you are willing to pay that price there are other worthy contenders. For example:

I for one would be very grateful if you purchase both the WE422A and the Telefunken RGN4004 and post your impressions.

I've had the WE422A (dimpled plates) in my ex-GOTL before and i find the sound very minty cool..not something i particularly enjoyed with the amp. And for the price, it was kinda disappointing. Having said that, other ears may find it enjoyable.

Thats interesting. DSG describes the GZ34 as "minty cool" but not the WE422a. The GZ34 is the other tube im interested in getting to brighten up my warmer headphones.
If I may ask,what headphones were you driving when you owned the GOTL+WE422a?

Was using my HD600s. Didn't really like the WE422 but have since sold off all my tubes and amp.

I have no experience with rectifiers - the GOTL amp I ordered has a solid state HEXFRED rectifier.
Somebody compared the HEXFRED sound to a certain Cossor tube. Can the HEXFRED rectifiers be tuned to sound a certain way?

@Monsterzero Might want to try rolling the driver tube and power tubes before the rectifier tube. I find the rectifier tube to make the least difference. Perhaps try a Telefunken 12au7 or Telefunken 12ax7. You can pay crazy prices for early and mid 1950's versions of these tubes, but the 1960's versions are still very good. My main system tends to be quite warm, so I like to have a Telefunken somewhere in the tube chain.

Take a look on Brent Jessee's site for details, and then see if you can find these tubes (cheaper usually) elsewhere:
