Lots of Completed DIYAudio and Nelson Pass Gear

Recommended Posts

Posted (edited)

During the last year, I have spent a lot of time building Custom Nelson Pass Class A Amplifiers, preamplifiers, and headphone amps and I need to start selling them. The amps I have been building are all from boards I get directly from diyAudio.com. I have listened to push-pull tube amps, SET tube amps, vintage amps, and even high powered class D amps on my Klipsch Cornwall III's, but always find myself enjoying the Nelson Pass amps the most.

Below is what I have available for sale:

 

F6 Power Amplifier in Silver Steel Chassis

- 25 watts per channel Class A into 8 ohms and 50 watts into 4 ohms

- 18 Volt secondaries for a total of 24 Volts. Used an Antek transformer and 60,000uf of capacitors. 
- Genuine Toshiba Matched JFETs. 
- Asking $1000 shipped. 


- M2x monoblocks in high quality black chassis with 10mm faceplates - 25 watts per channel into 8 ohm and 50 watts into 4 ohm
- This amp has daughter boards you can swap out like tubes for different input buffers (3 of 5 are included and 1 board just needs the leds to complete)
