Model 1

A Universal PCL82 SE Tube Amplifier Kit

(for more pictures, click here)

The Model 1 kit is a Single Ended (SE) tube stereo amplifier based on an audio tube PCL82 (16A8 equivalent). Design goals were simple: low cost but decent quality unit with a lot of features. Our thought process is detailed in the Background section of this site, but, basically, we wanted to create a product that is

- Perfect for DIY-ers who want to have many options to explore;

- Ideal for audio enthusiasts who always wanted to find out what the "tube sound" is all about, but don't feel like spending many hundreds of dollars for the experience.

FEATURES:

1. Headphones output

2. Two inputs option, no selector switch

3. Triode, Pentode or Ultralinear operation - jumper selectable

4. Open Loop or Global Negative Feedback - jumper selectable

5. Pentode g2 bypass - jumper selectable

6. Tubes paralleling option for increased power

7. Reconfigurable filament connections, options to accommodate various power supplies, even ECL82 (6BM8) can be used.
