Customer Reviews
Well, you'd be surprised how much you might do with this no gain amplifier. You should read up on it and if it seems you'd like to give it a try you will be rewarded with a new and lovely perspective.
It will show you what you need to know about your preamp. It will show you how a speaker can be really controlled. I use mine to drive a pair of high efficiency sub woofers because of the control afforded. It is a great tool in making music and taking a full assessment of where your stereo is at. I have built the F4, F5t, F6 and the Aleph J, all very good experiences and all still in service but the one that taught me the most about stereos is the F4.
All of the kits here are a great bargain and very well made. The gift from Nelson Pass and his supporters is not to be passed up. Build this amp! You'll be educated and it'll be fun!
Great service and fast delivery, as always from the store.
Excellent quality boards. Fast delivery
While repairing a channel in the F4 I had to unsolder and solder several parts repeatedly.
The board survived a hot iron. I've seen other boards come part after a single unsoldering of a part.
Excellent boards. Installed all components, biased up and working 100% and dead quiet
As always, a great product from the Store.
