Rectifier?

[dboul]

What the accepted rectifier for this setup? GZ34?

Would it be possible to setup a Boogie style dual EZ81 rectifier? Would it be worth it?

[Plexi]

About anything is possible..lol but for the price of 2 of those tubes,and all the other stuff,room etc..the GZ34 would be the way to go..just my opinion. And, when useing the octal,there are other tubes you could use,and try if one wanted to.

Yep, that's the logical choice. I was just curious about dual setup. I've read that it can do nice things and I like the Boogie dual recitifier even though that beast is a completely different animal than ours.

Besides the GZ34, I'm not real familiar with the performance characterics of other Recitifiers. What others would you experiment with?

[Graydon]

I thought seriously about using a pair of EZ81s but since they are not being made any more, I don't really like that idea. I am having a hard enough time finding those for my GDS Amps.

A GZ34 is logical but I fear it will not sag enough at all.

I suspect I will go with a diode rectifier with some sag circuitry.

Hey,

Any of you guys A/B a Weber WCA4 with the EZ81, how does it sound? Would any of you use one?

Or how about Weber Copper cap versions of these rectifiers?

Yeah, that was my thought also. I love the sag of the EZ81, it's really what add that extra bit of character to our amps. Do you think Ted Weber would be up for making a custom designed copper Rectifier for us?

All the best!

[Graydon]

Guys,

The Weber WCA4 is their EZ81 copper cap.

James, yes, Weber will make any custom copper cap you want. If you tell him your input voltage, your desired output voltage, the projected current and the desired voltage drop, he can calculate the correct design. You could do a chassis mount version if you want to preserve tube socket space. He might even have an adjustable version.

Graydon,
what about the Orion brand (supposedly from EI) for $11 from New Sensor?

[Plexi]

It may depend on the PT..but you should be able to get by on a 5V4..
the copper cap.. GZ34 being the one i'd go with.. the 5U4,might have the drop,but the current is more to run that tube.

heres a link that has some recto info..

I dont think I am the first person to try this but
in my current amp I am using a pair of 1n4007's
with 120 ohm 5 watt resistors in each leg.
Kind of a sag circuit.
I will let you know how it works out so far it works fine

What's their reliability like? I've heard a lot of current production rectifiers seem to suffer from reliability problems....

I sent them an email to ask about this tube but still have not received a response.

Do you know if it is a NOS or a newly manufactured tube?

[bnwitt]

Graydon,
I'm not sure but according to the tube store, it is a current manufacture by EI.

[DeanOwens]

i think graydon started to hit on this but ted has copper caps that are basically two in one. i think he could easily build a copper cap that would emulate two of these but be one cap. just a thought.
