Songbird : Choosing The Output Tranny

June 5th, 2011 · 1 Comment · calculations, Design, Songbird

Actually, it is already chosen. It is the existing 8k:8 center tapped primary that is already in the Crestline amp. However, I am excited by the choice, and at the risk of sounding like a dangerous lunatic, I’ll explain why. First though, lets look at a standard SE output section. That’s from a late 50’s […]

SongBird : Block Diagram

May 30th, 2011 · No Comments · Design, Songbird

Getting started designing an Amp means making quite a few taste decisions up front. The only thing you really know about the amp is there is going to be a guitar plugged into it. The next few moves are up to you before you can start with circuit design. The Bedroom Blaster. My goal here […]

SongBird : Time To Get Busy

May 29th, 2011 · No Comments · Design, Songbird

So that Medalist is working ok. Sound is a bit thin for lead work but that’s mostly because it is still too loud for me to crank it at full. Beautiful sounding amp if you pickups can put out some sound or if you boost leading in to the amp. So now it’s time to […]

A Little Status

May 3rd, 2009 · 1 Comment · Amp Computer, calculations, McTube, Songbird

Since I am failing to complete numerous tasks at once, I thought I would describe their status Amp Computer The problem here was banana cables.   At some point, the ‘Asshole Audiophile’ community got a hold of banana connections and now it’s damn near impossible to get banana cables at a reasonable rate.   I wanted to […]

A Game Changer – The Gibson GA 20 RVT Initial Review

April 23rd, 2009 · 11 Comments · Gear, Songbird

Introducing The Amp Computer!

December 18th, 2008 · No Comments · Amp Computer, Gear, Songbird

As I alluded to earlier, there are a thousand options that I want to try with the Songbird.   I only got through a third or so of them before I stopped writing and this is nearly the smallest simplest amp you can make (although I have a plan there too!) Now many of the options […]

Songbird : Requirements III – 2nd Preamp Stage

December 13th, 2008 · No Comments · Design, Songbird

2nd Stage Not sure here.   In fact, I have to admit to a bit of confusion.   See the output of a guitar pickup is roughly 0.5V peak to peak.    Maybe as much as a volt on a high output pickup.   The gain of the first stage is roughly 40 or more.    Now […]

Songbird : Requirements II – Pre Amp Bias

December 13th, 2008 · 2 Comments · Amp mods, Gear, Songbird

Ok, so clean power and rectified heaters and some other stuff were covered in the previous requirements post. Tube Biasing – 1st Stage As I understand it from my readings, the standard way of biasing, self biasing, is a complex reaction.   Essentially as the power drawn from a tube increases, the bias goes more […]
