I am collecting parts for my 200w mono amps "But"

WildOne · 24th May 2011, 02:15 PM

I have been collecting parts for a few large output amps. I want to do one 200w stereo all on one chassis and then I want to do a pair of 200w mono amps,

I know this is a huge adventure, I am up to the Challenge as long as I have good help.

I have the power. and the tubes what I need is a good schematic to go off of? Looking for a simple 100w per side stereo schematic to start! This will be the first one I start off with.

Tubes will be 6550's

I have some parts, But will need to order most of all the other parts needed,

Here is a few pics of the trannies I have to work with. The smallest ones are Chokes for the 200w mono's. then next up is the 100w OPT with labels and the the others with the label next size up is the PS for the 100w and then the monster 12.5lb 200w OPT and then the large Grey PS for them.

This is not going to be cheap! Just these are a big bite But they will be all custom hand made one of a kind amps made by me!

I may do a stone chassis and then do pillars of stone with the sockets inside for the tubes. And then carve all over it.

It will not look like all the others I have here. I am going way outside the box on this design. Way out!

I want to thank you for your help!

You might want to look at the new KT120s instead of the 6550s, but it may be too early to tell exactly how well they will sonically perform.

Parallel p-p KT90 is my current tack 2K A-A 40% UL taps...The electro harmonix versions which I have on a timer (1500hrs) are behaving consistently with 40W anode dissipation.
TungSol 6550 New edit, I found a disappointment, the best I've ever got is 150W from parallel pairs and they didn't last long. Modern day KT88's fall into the same trap, there is only one I found that can take punishment and that was the JJ version.

Maybe a good question to ask is why do you need so much power?

DF96 · 24th May 2011, 06:00 PM

Is this an amp for listening to or looking at?

If you don't, they sit there inert, cold, and unable to pass music through. Starting them up is critical to making them run.

They are for show and tell!

I want them to sit on top of the K-horns. I know I do not need no where this power but I am on this path and no stopping me now,

I should be able to get 25w x 4 of the 6550s with no problem? Don't you think?

Any idea's on a schematic?

Thanks

K-Horns? 10 watts will blow the roof off.
