====== Monastortion ====== Building Ibanez Mostortion clones based on the MT10 design of [[https://effectslayouts.blogspot.com/2019/12/ibanez-mt10-mostortion.html|Effects Layouts]]. ===== Transfer ===== Cut the copper board to size. Printed the design on photo paper with a laserjet printer. {{gallery> :builds:etching:pcb_transfer_preparation.jpg400x600&crop }} Ironed the designs onto the copper boards for about 4 minutes, iron on the highest setting. Soaked the boards in luke warm water for about 10 minutes and peeled off the remaining photo paper. {{gallery> :builds:etching:pcb_transfered.jpg?400x600&crop }} ===== Etch ===== Prepared an oven dish with warm water, about 45-50 °C. Then I mixed 500 ml of water of the same temperature with 100 gr of sodium persulfate in a plastic container and placed the container in the oven dish. {{gallery> :builds:etching:etching_preparations.jpg?400x600&crop }} Placed a thermometer in the oven dish and by adding hot water from a water boiler I can keep the water at the right temperature during the etching process. {{gallery> :builds:etching:etching_part1.jpg?400x600&crop }} Placed the copper boards in the plastic container. {{gallery> :builds:etching:etching_part2.jpg?600x400&crop }} After 15 minutes the sides were starting to etch off. {{gallery> :builds:etching:etching_part3.jpg?600x400&crop }} After 30 minutes the whole board had been etched off. {{gallery> :builds:etching:etching_ready.jpg?600x600&crop }} Took out the boards, dried them and removed the laserjet ink with acetone. ===== Drill ===== Drilled the holes, used 0.8mm for the component holes and 1.2mm for the pot meter holes. {{gallery> :builds:etching:drilling_holes.jpg?400x600&crop }} {{gallery> :builds:etching:drilled_holes.jpg?400x600&crop }} ===== Populate ===== Started with the resistors, MA165 diodes and jumper. Almost forgot the jumper. {{gallery> :builds:etching:populate_pcb.jpg?400x600&crop }} Finished it off with Wima film caps, Panasonic FC electrolytics, 2SC1815 transistors and Alpha pots. And the CA3260E of course. {{gallery> :builds:etching:populated_pcb.jpg?400x600&crop }} ===== Result ===== After testing I pulled out the MA165 diodes. They're probably fakes as they sounded like those thin French pancakes. Replaced them with 1N914's which I also used for other Mostortion based builds. Sent one to Michiel from [[https://www.muziekweb.nl/en/Link/JK230208/Filling-up-the-room|Stillwell]]. I'll probably keep the other one myself, I might mod it the Danelectro Roebuck way with an extra switch for LED clipping.
