EL84 Amp - Baby Huey - Page 100

I do not think the Red Light district will be an improvement on the Baby Huey, do yourself a favour and stick with the one you know.
I have listened to many partial feedback amps and have heard a RLD and it didn't come close.

Just my personal opinion though.

Thanks for the tips, at the moment I need the construction practice and the practice at building different amps, plus the RLD has a lot of literature with it. I was also thinking about something bigger like Allen Wrights PP1...

... could you suggest something?

The RLD has a classic global feedback sound. Think of your expensive SS amp , but better of course. The friend who built one never really used it after building it and he has very very good taste in equipment.

Allen Wrights PP1 would be a fantastic project which couldn't help but impress.
There are a few partial feedback amps that have been designed on this board and a bit of digging should lead to some inspiration.

Just use the RLD bias method into the BH !
Should be the wedding of the year

That's a cool idea! I really want a BH for myself, so when I build another one ill certainly do that. Havnt yet built anything with octal valves, so i might go for something bigger like the PP1, or maybe a Tubelab design.

Was going to have a little break for a while, ( to learn some theory

) but this sounds like a nice tweak before I go to fixed bias. And then there's all those red led's left over from the Chrismas Tree, sooooooo......

Charlie,

This might be sidelining you a bit but have you thought single-ended? EL84 or ECL86 based consoles can be had very cheap on Ebay. Ripping out the parts will show you how the "oul hands" did it, then screw the lot to a wooden board. One 12AT7 and two EL84's gets you an RH84. It's an interesting comparison between the RH84 and the Baby Huey.

Shoog,

Forthright personal opinion based on personal experience is good to hear, so thanks for that.

CSlee · 4th January 2011, 08:44 PM

Ive definitely considered single-ended, the first amp I built (second being the BH) is a SE 6DT5, and I really love the sound, very different to the BH.

Cheers

Charlie
