adam 2006-05-18T22:23:52Z 2006-05-18T22:23:52Z A full subminiature amp [7] tag:amps.zugster.net,2006-05-18:32de2542b0f58dd9ca221a5db9e3dc4e/f8b76cc03130edef4c6debe4d7de005b Jon Anderson just let me know about an amp he’s built using 6112 and 5902 subminiature tubes. The 6112 is a dual triode (mu around 70, I think, like a 12AT7, and the 5902 is a power pentode. He’s posted a schematic and sound clips – it’s sounds great! Go check it out.

adam 2006-03-01T18:23:48Z 2006-03-01T18:23:48Z Four Different Overdrive Pedals [1] tag:amps.zugster.net,2006-01-09:32de2542b0f58dd9ca221a5db9e3dc4e/6a044049e3b5a9a9a97b7222183490f2 This pedal update has an interesting twist – the site Runoff Groove has taken several classic tube circuits and adapted them as pedals using MOSFETs. MOSFETs actually behave in a very triode-like manner.

They’ve taken the Matchless DC/30 design and adapted it as the Matchbox, the Dumble Overdrive circuit as the Umble, and the Boogie Mark I as the Uno. In fact, there are even more – check out their articles page.

These look pretty interesting, and I’ll probably build one, or even all three, of them at some point.

Ted Woods also tipped me off to another tube pedal, the Stephenson Amps Stage Hog, which uses a 12AX7 and a 12AU7 and can be operated as a tube distortion pedal or a practice amp.

An automated cleanup process deleted the .htaccess files, so all the redirects weren’t functioning for a bit. It’s been fixed.

We now return you to your regularly scheduled soldering.

adam 2006-02-07T18:47:00Z 2006-02-07T18:59:47Z Parts for Visio schematic and layout diagrams [1] tag:amps.zugster.net,2006-02-07:32de2542b0f58dd9ca221a5db9e3dc4e/faf5fe30b32394ee48a4f46a1776d180 If you use Visio for drawing schematics and layouts, I just uploaded a huge collection of diagram components for both. It’s a ZIP file full of Visio files which you can copy & paste out of. Don’t miss the fact that many have multiple pages.

This used to be up on my old site years ago – thanks to Carl for reminding me of it!
