Someone help me out with transformer/choke placement. I read that the goal was to make sure none of the laminations were in the same plane. If you look at the way I have my transformers and choke positioned, you will see that I have accomplished that. The laminations of the choke and OT are perpendi...

I ordered them accidentally last time. Just seemed like the right choice.

Okay. I thought "can" just described the can-like packaging. I didn't realize a cap with axial leads was not considered a can cap.

Wait...hold it..."can caps"? Aren't all electrolytics can caps?

Okay, so it sounds like I'm fine as long as I don't go through with my plan to lick the capacitors every time I play. I'm not using a standard chassis. I'm using heavy aluminum channel. I tried to upload a cell photo, but my stupid AT&T phone service decided to take 9 days to get the shot to my emai...

I'm building a 5f6a Bassman clone (head only), but I'm not using a kit. I'm running into some confusion about the filter caps. I can't find out how they're usually mounted. I've found various photos of what appear to be filter cap arrays covered with little metal boxes. Questions: What's the best lo...

I am fairly sure I got my grounding concerns from this page: http://www.aikenamps.com/StarGround.html It looks like I overgeneralized what I read. They have specific advice for OT and PT grounding. Samples: Do not ground the output transformer common to the chassis and then ground the output jack to...

Bought some structural aluminum today to see if it will make decent chassis. The big piece is 6" Aluminum Association channel. The smaller ones are 4" square tubing.

I just took the schematic and ran with it. The hum is greatly reduced now, but I think I could improve things by doing away with my Twister-style grounding scheme. Here's a link to the page where I found it: http://www.harmonicappliances.com/powerman/powerman.html I really liked the sample sounds. I...

I think I got a little paranoid about hum after I built my second amp. I put like 3,000 ground wires on the eyelet board and grounded them wherever I felt like it, and since then, I've been opening it up periodically to undo the damage. My first amp, the Firefly, doesn't hum at all. But it does osci...

They didn't supply the reason, but if I can find this guy, I'll definitely give him a hand. They can't fire ME.

I am new; thought I would say hi. I've built two tube amps: a Firefly and a "Powerman." Both are small. The Powerman uses two 6021 submini tubes. I am currently working on a Bassman (5f6a) clone, from scratch. It's just a head. I also have a 1x12 cabinet I built from a plywood sign and a 12" Weber S...
