First Watt M2 Audiophile Amplifier. Nelson Pass is a genius! I consider his amplifier designs absolutely brilliant. This is the best sounding amplifier Ive ever owned. The M2 is rated at 25w/8 ohms and 50w/4 ohms. This amp produces so much current it even drives my Magnepan LRS! I am the second owner. Unit is maintained in an air-conditioned, pet free environment. Buy with confidence, Ive been a member of the other audiophile site for 20 years. I dont have the original box but will be well packed (see photos). CONUS only.

First Watt F5 (Clone) Class A Amplifier. Up for sale is an amazing Class A amplifier and desired by many. I have built this amplifier out of curiosity as I have been told it is absolutely amazing, and it is, but I still prefer my Aleph . It is built as dual-mono, and each channel it is powered by a 200w toroidal transformer and filtered with 66000uf per rail (264000uf for both channels) CRC filter. It has a soft starter with thermal protection, speaker protection (powered by a 3rd transformer), rhodium plated RCA and banana sockets, input and output wires are silver plated OFC . After 3 hours of use, the heatsinks reached 45 Celsius and the power transformer 49.5 Celsius with a room temperature of 21.5 Celsius. There are some extra holes because I used to have the Aleph 3 (spare unit) installed before Collection only please Any questions please feel free to ask

NELSON PASS FIRST WATT F4POWER AMPLIFIER The First Watt F4 is a classic Nelson Pass/First Watt design with JFET inputs and MOS-FET outputs. However, as with the other FW amps there is a twist here, namely that the F4 has no voltage gain. That means it’s essentially a buffer than can provide a full 25W class A output. its low or no gain so needs a preamp with a decent output Track Page Views WithAuctivas Counter
