Hi jack,

may I know what does it mean "Note -- these resistors must be chassis mounted" ?

Are the kits for F5 still available ?

The Caddock MP930 and MP915, while nominally rated at 30 watts dissipate significantly less energy when not mounted on a heat sink -- here's the link to their catalog page:

The F5 kits use the Ohmite TWW5 -- which has a small footprint and gets the heat off the board quite well -- if you've seen pictures on Janneman's PAX amplifier he appears to use a similar device. People have sent me their boards using radial "boutique" resistors and they are often scorched.

I have F5, F4 AND F3 kits in stock.

Burning Amp parts

I was busy matching MOSFETs during the New Jersey rainy season! Ergo I am able to supply the matched sextuplets for the BA#1 output stage in either Vishay(IRF) or Fairchild flavors. I can also supply a limited number of driver stages with matched 2SJ74's...kits of parts will be available next week.
