Hey Glenn,
 
any idea why those 5Z4G CV1863 keep blowing up in my amp? They do work fine in Clayton's amp.
 
Thx!

The 5Z4G is only good for 125ma your amp has two 300Bs at 70ma each and two C3gs at 20ma each
This is 180ma plus recharge current to the capacitors. This is why they are blowing up.
Clayton's mono block amps only have one 300B and one C3g per amp this adds up to 90ma this is fine
for a 5Z4.

I am not a tube addict, I don't like tubes, I really don't like tubes, no more tubes, I am going SS..........................

Do you want me to build you a semi SS amp? A 6SN7 driving high power mosfets
120 watts output into a 8 ohm load nearly twice that into a 4 ohm load.
You don't need to buy any 6SN7s I know you have them or 12SN7s or 25SN7s will all work.
No tube addiction only two 6SN7s   More power then you will ever need easy to blow your speakers up ?

That actually makes a lot of sense. Math, who would have thought I'd ever need it.

Thanks for the info. The bullethole plates in the 5Z4G are the prettiest plates ever though. They're now being used as decoration.

No......No.....No.
 
You already made my addiction much worst by introducing me to the 25SN7 and 6BL7 and 6336 and all of them just in one amp..........
 
Clayton can I hide inside your seashell please?

You should have him do the hybrid for you. It will drive Maggies. 240W into a 4 ohm load driving the Maggie 1.7 or better yet the 3.7

Welcome back!
 
My question is related to the WooAudio WA5. Last time we spoke on this, I brought up the wrong version of the Siemens tube. Would I be able to use the C3g with adapter as a drop in tube for the 6SN7 inside the WA5? Thanks!

Yes. There's room for you. It sounds like the ocean in here. Very relaxing.

I think Glenn wants me to get locked up in a lunatic asylum soon.
 
That's why I need Clayton's help, very nice hide out!
Does it come with a mermaid?
 
Tektron are not bad speakers either.

Not that easy but I suppose it can be done.

Common Stavros I am trying to help you a amp with only two tubes.
I know I have been a bad boy introducing you to new Tubes with this new OTL  amp.
have to ween you off tubes slowly or you could end up in a lunatic asylum if you go cold turkey.
Your neighbors might not like this Hybrid amp though.
Have to think of something else Cookies were no good especially when I send Tubes and cookies in
the same box.  Even put tubes in a cookie tin that was bad but it worked and no tubes got broke.

Have to find out what the plate resistor is on the drive section of the 6SN7
The C3g has to have enough current to work properly driving a 300B.
