Built this Ampeg B15N clone over 10 years ago. Based off the details / info from https://www.thallenbeck.com/blog/posts/d-i-y-ampeg-b15n-fliptop-clone/
Amp has Fender 6L6 tubes, RCA 6SN7 (original used a 6SL7 in driver seat and 6SN7 as PI, but I had two 6SN7), and an RCA 5R4 Rectifier.
Unit originally was a 6L6 / 6SN7 / 5R4 based Carillon amp powering a Church Bell. The power supply reused the original power transformer and tubes, while the output tranny was replaced with a Fender Hot Rod Deluxe Transformer. There were 5 more octal tubes in the original amp (two of which were more 6L6 output tubes) that were not needed for the B15N, so power transformer has lots of spare power.
There were a few minor changes, but most of the circuit is the B15N circuit on the website and attached schematic. Volume, Bass and Treble pots, as well as another pot on front corner for setting feedback, and the one on top to add additional resistance to Cathode resistor. Single input only, Cathode Bias (common 300 ohm) instead of Fixed Bias were biggest changes. Don't remember as this was over 10 years ago. Amp is bolted to a Bamboo cutting board.
This is a working amp and sounds great with my guitars.
Looking for $250 + ship. This unit is heavy.
