What is the result of higher impedance in SET?

Do you know any good book or web resource on SET design (specific to 300B, 245, 2A3) for amateur DIYers? Not just here is the schematic, now go build it; but explaining each amplification stages and calculation of output, etc.

Hi:

How much do you know about basic electricity?

An old (pre1960) ARRL (American Radio Relay League) Handbook is a good place to start if you are new to tube-electronics and have basic Q's about how things like transformers work. Can be had on ebay for about $10-15.

I have a fairly large collection of DIY tube sites fairly organized w/ live links in Word format. One part of it is a collection of sites I think would be helpful for beginners. It also includes a list of about twenty online articles about audio transformers you might find helpful (several very good for the basics) given your question. It would at least be a helpful place to start. Drop me an email if you would llike a copy.(I cannot send it through agon e-mail because it won't take an attachment) Some of the books I have found useful are listed in the outline.

Here is a simple article on OPTs that explains some of the design tradeoffs. http://www.aikenamps.com/OutputTransformers.html

Thanks, Clueless. I forwarded my email to you.
