[Amps] 833A/GU-48 x4 Amp support

[Máximo EA1DDO_HK1H]

Hi all,

I am not an amps expert but I am thinking to build an amplifier using 4 x GU-48.
I guess GU-48 is equivalent to 833A, not sur if all specs are same.

This is trying to get an amp "looking beauty" and good audio quality, it is not looking for extremely high power. I already have an amplifier (Acom 2000A) i can use as driver.
Something like this, but HF; http://www.luxurylaunches.com/entry_images/0511/17/Audio-Power-Labs-833TNT-tube-amplifier-1.jpg

Gates BC-1g is an example too; http://w5ami.net/bc-1t/833.glow2.jpg

It could be monoband amplifier for 20m, perhaps 40m too.

I thought in GU5b and GU-81M before, but I guess GU-48 is better because needs no specific blower and is triode (easier to build).

Please, Any of you have sperience with this kind of amplifier?
Any squematic?
Recomendations?


Thank you very much
