EHX - Hot Tubes - 1590B PCB Layout

[Scruffie]

My Second Attempt Ever at a PCB Layout... Not The Best Layout In the World I'll Admit but it was a Tight One!
Not Checked But Okay at a Glance...

1590B with Onboard Pots, Pots Mount On the Back of the Board... 3 Jumpers but it was the best I could manage.

Based on the Gaussmarkov Schematic - http://gaussmarkov.net/layouts/hottubes/hottubes-schem.png

Board Measures 53.34 x 53.34

Whether the layout is error-free or not (and I haven't checked, but thanks for posting it), a Hot Tubes will probably fit in a 1590B.  Just make sure you leave room for an adaptor input and that you socket the 4049.  The HT will run off a 9v battery - I've been doing so since the late 1970's - but it won't do so for very long.

Well if the layout is right, it'll definitley fit in a 1590B and there's room for the socket round the 4049 too.

Just touched it up a bit now too.

Well... i've either improved this layout or made it worse, you be the judge.

Will still fit a 1590B with a battery though, now has the SPDT mounted on boards and still onboard pots (All Mounted on the back of the board).

J1s connecting point is hidden between R3&4 on the Silk screen, there'll be room though as the resistors are oversized.





Unverified and the board measures 54.61 x 53.34mm
