The offending tube has a rattle when I shake it.  I have a pair of compatible 5ar4's, so I popped 'em in.  After the soft start, the right 5ar4 sparked and the amp blew a fuse mad.gifmad.gifmad.gif.  Well, good thing I did not pack up my ASL mg-head OTL yet.  Any of ya'll have this problem?  Sent an Email to Woo, I'll let all of you know what he said.  

 

Your best bet is to get a pair of 596 tubes but these are starting to get hard to find.

Next best thing would to get a pair or 5U4GB these are stronger then a 5u4G

I know nobody likes the 5U4GB it is not as pretty but a much better tube the 596 and 5U4GB

are electrically close.  If anybody says the 5U4GB don't sound good I say BS.

One thing when you buy new rectifiers they have to be the same brand and vintage

or the filaments won't worm up evenly and one tube will blow up

You know how such matters usually go. Customer is having issues with bottles of pricey Champagne going flat prematurely; returns to importer to complain.  Importer turns to Champagne House to raise the issue. Told their is nothing wrong with production methods and said customer must be using dirty glasses or improper storage.

 

Customer gets frustrated after trying new bottles at own expense - same results. Decides to switch labels before going broke.  With no changes made from the importer to the manufacturer. Or something like that...biggrin.gif

Good analogy. I'll drink to that! That's why this thread is so important. When amp owners can help each other find that great bottle of bubbly when others have gone flat.

I shouldn't have to drop what I'm doing, just to tell a manufacturer "I don't care if it's made from wine, if I wanted wine I would have bought the bleepin' bottle already!"

I am using 2 Mullard GZ34s in a Cary SLI80 integrated amp.  I have not had an issue with those.

Do any of the Woo amps have multiple inputs?  I am looking to upgrade amps and I'd like one with two inputs so I don't have to move wires every time I go from digital to analog and back. 

Thanks in advance

When in doubt, specify. You buy and Jack will deliver. Some owners have different needs and simply have Jack address them.

So they will put two inputs on if I order it that way?

It'd be proper to make the request. Then, once the dialogue is opened between you two: he can confirm or maybe even make a suggestion.

Thanks

I  went to their site, some have balanced and RCA inputs which will work great, analog= RCA and DAC= balanced

post #24568 of 30402
@awsanderson. My WA22 has those.. But I run my vinyl front end balanced, and my dac unbalanced;)

I've had EML 5U4Gs (mesh), bought new, using daily for 3 months now in my WA5LE, not even a hiccup.  They sure sound amazing.
