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 design my dream SE bedroom amp. I’ve mentioned decisions and design considerations before, and following the songbird category will let you slog through all that if you like.

I’ve changed my mind on a few things and come up with some ideas. I’ll sketch here and some of these will be explored at length later.

  • Low Power – This is a bedroom rocker
  • Not going to build it as the amp computer, but will provide lots of switches and options. Too many, almost surely but that will be ok.
  • I’m going to convert my Crestline Skylark, rather that tweaking a 50’s blonde Skylark. Couple of reasons here :
    1. I am adding a second gain stage, so I need the space.
    2. I have one here
    3. The transformers are perfect for what I want to do
    4. I want the extra space to work with, the chassis is almost double in size.
    5. I want the 10″ speaker (minimum)
  • Second gain stage using a remote cutoff Pentode
  • Pentode, Triode and lots of configurations for the output tube mode

The big thing here is the realization that the Crestline Skylark sitting next to me right now has half of the things I want in my new SE amp. Bigger speaker than the 8″ in the blonde, Plenty of space and lots of good iron. I was looking at damn near 200 bucks to just put iron into a box. For reasons I’ll make clear later, I have everything I need in front of me.
