My NEW AMP being born

[StukaJU87]

Flo, man. That looks great. I envy the guys that can build like you , Pete and JG and actually KNOW what you are doing.

Jeff set a couple early chassis pics.

[Infernal Death]

Very nice. Can't wait to see the next build progress pics.

Here is a pic of my work. Just confirmed that all the transformers and tubes are fitting to the holes i drilled



Oh yeah i suck at taking pics haha.

Well, Jeff just sent me pics of the completed board. Here ya go.

No Problem. I also found it very useful when i first discovered it. I always buy my tube stuff there, great shop that i can recommand although i guess not a good choice for you american guys.

That was an interesting chart. Thanks for posting it.

This is something I would never have thought of doing.

I hope it all goes to plan.

There is a german tube store which has a nice info pdf on this:

http://www.tube-town.net/info/doc/tt-tubemap.pdf

I picked the tubes while reading this pdf (cool read, english and german). The chinese preamp tubes are mentioned as TT tubes. (those are labeled from the store, TT = tube town). As for the preamp i didn't want to go the "extrem" setting so i didn't choose a TT for V1. Tungsols seem to be a great way to get much tone and not over the top extremness from the preamp section. For this i have my rectifier.
But i have to say i haven't used a Tungsol tube yet so it's also a bit of a experiment. Nice thing is swaping tubes is very easy and fast. I still have some other 12ax7 laying around.

Dagnall sounds right. I believe they built transformers for Marshall and many original replacements are Dagnall. So i guess that's a nice choice for your amp.
What's your choice of tubes ? I guess Svetlana EL34's ?
In my BadCat Clone i will use 2 Svetlana EL34's, a JJ GZ34, 1 Tungsol 12ax7 for V1 and the rest of the preamp tubes will be some chinese 12ax7.

It will have EL34's in it. Not sure of the brand. He has a shop full of NOS tubes so I am sure he will be picking a decent set for me. I am not sure what brand of preamp tubes he will use yet either. Like I said, he has literally hundreds of boxed tubes of all brands dating waaay back, so I will have the option of trying others as well.

Can you explain the reason for using 1 Tungsol in V1 and Chinese in the other spots? You have to spell it out for me, I am green when it comes to electronics.

I could not find the emails with the tranny details. I remember the name Dagnall? Is that right? I think he said the power trans has a tap for 80% and 100% power. I don't know. It is all Greek to me.

that cab looks great - can't wait to hear your review!

Well, I know that the 2203 does not have the gain I really want, but we knew that going in. Ideas are in the works, but not until the amp is tested for a while. Thanks on the cab. I always like the white on the old style boxes.

Nice choice of amp and color too. I've got something similar myself but yours will be a bit classier I'd say.

Yours looks great. Classier? Nah...just different.

Flo, I have to look at some of my emails from him. He told me the type of transformers he bought, but I forgot. Let me go check.

That's going to be SHARP when it's done!
