IT WORKS
« on: March 27, 2019, 01:25:00 am »
This post is to simply say thank you to everyone for their help, suggestions, and banter while I worked at finishing this thing.  This was my first amp build and didn't know a resistor from a capacitor last October.  I had gotten back into guitar this past summer and I broke my digital interface I was using as an amplifier run into a studio monitor - it was a crap setup.  I wanted to get a good amplifier, but knew I would never be able to justify or be allowed spending that kind of coin on something like that when my kids eat all the money.  I decided the only way to have a nice amplifier was to learn how to build one my damn self.  I started to study schematics and classic amps and narrow down what I wanted to build and scoured the internet looking for cheap parts.  I found a random craigslist ad for a bunch of amp stuff from a guy that was moving, and it was the mother load.  I didn't know if any of the stuff worked, but I wound up leaving $300 with him for 130 tubes, an old tube tester from the 50s or 60s, thousands of passive components, hardware, transformers from various decades, 8 or 9 speakers, several empty chassis, a few cabinets - basically everything that I would need.  I bought a weller soldering iron for 30 bucks and started learning to solder.  As soon as I felt comfortable with the iron in hand and enough studying to feel like i wasn't going to die doing this, I got to work.  Long story short, after a failed attempt to find an acceptable way to make an old 450-0-450 transformer from an old organ work, I just bought a used weber pt that they market as being for a champ, but I thought its specs looked well suited to a 5e3 inspired pile of scraps.  I swapped out the transformers, fired it up, and it lit up but made no sound..... 5 minutes later after realizing that the ground bus wire should probably not flaccidly drape across the tip contact of your input jack, IT WORKED!!!!!  It sounds pretty nice, its ugly as shit, and here it is in all its glory-  I give you .......

BUTTERFACE!!!!
