Simulating Bevois Valley Morgan Jones in LTspice

Hi everyone,

I'm new to diyaudio.com so please let me know if I started this thread in the wrong place.

For a long time I've been wanting to build my own stereo amp and have been educating myself on how tube amps work and how they are designed. I still have a lot to learn.

I have installed LTspice and have modelled the schematic of Morgan Jones's "Bevois Valley". This because it might give me more insight in how electricity behaves and flows through an amplifier.

I can't seem to get it working. I get the error: "Time step too small".

I simplified the voltage regulator because I want to concentrate on the actual amplifier.

For the transformer (Hammond 1615) I have used the model of Robert McLean, using his spreadsheet.

Does anyone know what I am doing wrong?

Please let me know if I don't provide enough information or anything. I'm here to learn.

I will include my LTspice schematic with the necessary .inc files.

Thanks a lot, I will really appreciate any help!

Bart

Some screenshots

I think some screenshots of the schematic in LTspice and on paper will be useful.

I can't imagine what has happened here. LTspice won't open your .asc file. Asc files, even encrypted ones, are ASCII (i.e. plain text) files, and when I had a look at your file in a text editor I found that it is anything but plain text.
