The SteamAmp II From Copperstream

The SteamAmp II  from Coppersteam.com is the second iteration in the SteamAmp line and we think it looked great and certainly steampunk_ampworthy of a mention in Hifi Pig’s news section. Its circuit follows the original, and is based upon the S5 Electronics K12G Kit. The power supply caps and signal coupling caps have been upgraded, and snubber caps have been installed on the heater circuit. The output transformers were upgraded with Iron from Edcor.

The amp puts out 8 watts per channel, and has 5 inputs; 4 RCA pairs on the back, and a 1/8th jack on the front for MP3 players and the like. The volume is controlled by an 11-step attenuator. The tubes are 10GV8 Triodes in push-pull configuration.

The chassis is solid 3/4” Black Walnut with 1/8” Copper plate top and front panels and the transformer cans are constructed from 3 and 4” copper pipe caps. There are 4 glowing rods inside the glass window on the front that are lit by UV LED’s when the unit is powered on.

This piece was built as part of a commissioned system for a gentleman in Connecticut and will be finished out with a matching set of speakers.
