Hammond 272DX PT for which amp?

[garytube]

Hi all,
I have a Hammond 272DX sitting around collecting dust, so might as well build an amp with it. It is 300-0-300V @125 mA with filiments (5v 3A)(6.3 4A). I'm thinking tweed deluxe, but could I make a 5e5 pro with this transformer, or do I need a bigger one for 5e5?

I'd think that'd work for a tweed deluxe. I was wanting to make a tweed tremolux (5G9) and that transformer might have been a little light for it.

Looking at the tube data sheet for 6L6s, I don't think you'll get enough current from that PT for a 5E5 + 2 12ax7 and a 12ay7.

Although the B+ will be a little low for a 5E3 with a NOS 5Y3GT, it will work fine
for one using a Russian 5Y3GT or maybe even GZ34... if you also use a slightly larger biasing resistor, such as a 300 ohm to 330 ohm with the GZ34.
The Hi-VAC is lower but the current rating is higher then the stock 50's 5E3 or the 5G9.

Heck yes, and you won't regret it! I love mine, my commercially built amps are gathering dust. It does clean, grind, quiet, loud, and everything in between.

I found the tone I like with the amp knobs and pretty much leave them alone now. I vary my picking and guitar knobs to change the tone. Don't the meager three knobs fool you, this is a versatile amp and it has made me a better player for it.

Good info, thanks. You nicely included the bit about the 5G9 for me, I see

When tube data sheets give the current that the Ia (for example, the Ia for 6V6s at AB2 p/p here: http://tdsl.duncanamps.com/show.php?des=6V6GT That means that the 6V6s want to see about 70ma or is the hottest you want to run them?

So if I am reading that right, a 5E3 would need about 75ma to properly run the power and preamp tubes? How do you determine the optimum voltage? The 5E3 schem doesn't have voltages. So how do you figure that as you did above?

I guess another question is about voltage drop on rectifier tubes (and if there is some good resource for me to find the answers myself, I am interested, I have the RDH and stuff like that but it's very hard to wade through for simple questions like this). I have seen the datasheets, with the voltage drop curves and all. What happens to the voltage? It can't just disappear, can it?
