I am in for 1 on the wiki. Why is there not more interest in the F2?

Maybe its because you can get about any FW amp known to us right now except F2 on PCB.

The list of 33 so far is not bad. The F3-F4 list took a while to reach 50 units each.
The F5 I think took a few days only.

Even a like me can build an F2 point to point. My first Pass amp.

This is reason enough however for anyone to want to build an F2 with a real PCB. Mine looks like

Hey fella's,

We only need 15 more boards to make this happen. Come on, you know you need a pair to complete your F-series collection.

Some recommended reading. F2 is good for full range drivers typically.. like fostex lowther, tang bang.

http://www.firstwatt.com/downloads/cs-amps-speakers.pdf

The heatsink's are likely most expensive part. Needs to dissapate some 100 Watts each channel constantly for this model. Transformer second most expensive?

PCB's 30 bucks or so, parts each channnel 30-50 dollars each.

Connectors drill taps, etc casing metal, the ski is the limit.

A more universal amp maybe the F5.

That being said - F2 circuit is pretty simple to roll. A voltmeter and a fire extinguisher are recommended.

I am in. That amp is so special. Just the thing for fullrange speakers, so 1 set for building and 1 set for the growing PCB collection



Edit @HaLo6, this is a specialty amp with 5 watt output power and no damping factor, so it is not useful for the usual speakers with a crossover. The F2 amp need efficient singledriver speakers to sound good.

Anyone volunteering to do a Sonido GB??
