I've brought back my Super 211/845 SET amplifier featuring several substantial updates in both sonics and reliability while maintaining the absolute balls out SET presentation provided by these tubes. NOTE: Please use CONTACT US for ordering.

Features

• Allows use of either 211 or 845 power triodes by changing bias settings via two switches
• Massive output transformers allow bass down to 20 hz and extend beyond 20khz
• Can be driven directly from a 2 volt source such as a DAC or streamer with built in volume control
• Balanced inputs can be added upon request
• 6SN7 input stage

Redesigned from the ground up! Now featuring an over-built outboard tube rectified and regulated power supply. Many updates to the circuit and componentry throughout to punch well above its weight class! NOTE: Use CONTACT US for ordering.

Features

• 1 Set of Stereo MM Phono inputs
• 1 set of stereo line level outputs
• true analog design
• 100% point to point wired
• (2) 12AX7's for RIAA correction and gain

A brand new product due to many requests for a small, single box stereo tube amplifier! This amplifier uses EL84s in triode-strapped mode for just over 2 watts per channel of single-ended sonic bliss! A single 6922/6DJ8, 12AU7, E180CC or 12BH7 is used as the Input and driver stage for both channels. I've fitted this amplifier with many upgrades- Miflex copper foil capacitors, a toroidal power transformer, Transcendar output transformers and lifetime rated film filter caps to name a few! This amplifier can be used with or without a preamplifier. Please use CONTACT US for ordering.

Features

• Single EL84 per channel
• 6922/6DJ8, 12AU7, E180CC or 12BH7 driver stage
• Stereo Output of 2.3 watts per channel
