“Mundor/F5” - Pass F5 inspired with advanced boards

 


















I was vey impressed with last F5 I built using Jim Audio boards. The amp sold before a I could start construction. The build was a big step up from the F5 before by upgrading the filter caps to 88,000uf of Mundorf MLytics and the toroid tranni upgrade from 160W to 300W. The total presentation of that amp was beguiling.

Here is my build based on what I thought maybe the best amp I have ever heard. Ounce more 88,000uf of Mundorf MLytics audio grade caps at over $300 for caps alone. Same upgraded Jims brds. and as before all Cat5 twisted pair hookup wire. This amp shines. Given the right music you are challenged to think something so compact and unassuming can generate such presentation. It’s a 25W Class A simple amp. Bass goes easy to 30Hz, mids are transparent and treble clean and controlled. Compact and astounding.
