Phaser with Script MOd

 

 An MXR Phaser with script mod, includes a wee circuit which allows the 2 LED's at the top to oscillate with the phaser speed. 2N5952 transistors are not essential. I've used a quad of matched 2n5457's from Tayda electronics and it sounds equal to my real thing. That jfet tester is essential too. While I had it in working order with the 2n5457's, I also tested J113's, and /j201's with good results. Just a bit of tweaking  to the bias trimmer for each to find the phase zone. This has replaced my original.

A new phase of box design. The Tayda prints were great, and I was honestly just wrapped that I cracked the Inkscape/ Scribus solution to printable PDF's. But they weren't Shed Peddy enough for me. I wanted more industrial and hand-made looking. Having already done a bit of etching with PCB making. I had a half bottle of hydrochloric acid left over from when I painted the garage floor, and I still had an old toner printer in a cupboard store. Watched some you-tube how to's. This is my first attempt.

Etch design- Inkscape. Etch job was below average for me and its .taken some experimentation with a stopwatch about how long I spend ironing on the mask and how long and strong a solution I etch with. I still get some rough edges and bits where it gets through the mask, but I find it really adds to the handmade in the shed look I think I'm heading toward
