Default TCJ Push-Pull calculator v2

I was considering purchasing TCJ Push-Pull calculator version 2, but the website has a bunch of broken links where the product information should be. I get no response from the support email address. I would like to have a tool to automate calculations, but don't want to gamble with my hard earned money.

Anyone own this and is willing to share what it does so that I can decide if it is worth buying? Screenshots would be appreciated.

I use it. Very easy to use. Would it be more approprate to email you some screen shots?

That'd be great. I'm particularly interested in which tubes it has curves for. Also, I'm hoping it does on the fly calculations for power output and you can drag load lines around and print things out and all kinds of cool things like that.

Thanks in advance.

There are 57 tube types from 6h30 to 45 and SV811-10 to 6B4 and 6SN7

I am runing into forum max file sizes. So I am only showing a portion of the screens

Well, it looks handy and doesn't cost too much, maybe I'll pick it up.

Thanks for taking the time to post the screenshots.

You can also add user defined triodes or triode connected pentode/tetrodes to the database.

I just downloaded this. I have been skeptical about its usefulness for some unknown reason, and indeed, there is a lot that it doesn't do -- no pentode or ultra-linear circuits, no ultrapath caps, no just drawing a schematic and getting an analysis. However, I've learned more about push-pull amps in the last two hours just by tinkering around with some circuits than in months, ne years, of books and online reading.

Worth $100? perhaps, but easily worth $30. Most important lesson thus far -- there is just not that much power to be drawn out of a pair of Class-A 2A3's ...
