    Hello Guys, I am documenting a couple of projects that I have been thinking about for a while. I have a couple of new PAM chassis that I was wanting to do something with.
    I decided to do a MONO TCLA Preamp and a 78 Phonostage to Compliment my latest Erhard PAS Build.
    Here's a link to the Imageshack pictures of that build: https://imageshack.com/a/uoaW7/1
    Here is a view of a PAM that the new circuits will go into: Clicking on the thumbnail should bring up a full size picture.

    1st up is the Mono TCLA Preamp. Here are the Thumbnails of where I am at:

    The Main PWB assembly will be in the original PAM preamp location and the Power supply will sit behind the AC input.

    2nd is the 78 Phonostage based on the modified Cornet by Hagerman. Here's a link to his article: https://www.hagtech.com/pdf/monogram.pdf

    Now these 2 circuits could have been put into a PAS chassis, but I had the 2 PAM chassis and thought it would be neat to build the separate units.

    Let me know that you think and any comments are welcome.
