Cant't use rn60, I use rn55 and there are 0.6w that can fit, for example vishay mrs25 , te lr1 series. You can buy from mouser rs etc. For electrolytic, I user the one that fit pcb, panasonic fc are small enough.
Cool build Tony!
Are the knobs on the aft panel for source selection?
What did you use for rectifiers( I think that's what I see on top of the xfmr)?
You used rn55s for 1/4w resistors? But they are rated for 1/8w. And for 1/2w you used mrs25s? What did you use for 1w?
carbon film resistors were used....i have tons of them in stock...china stuff mostly..
the pots control volume level so i can connect the cd player directly..
i used inline sanken 50A 1000 volt rectifiers, i did not use a center tap that is why two rectifiers were used..
something like this:
Tony, looking good !!I like the clamping method that you use to fasten the transistors, much easier then have to drill a hole for each transistor.
my consideration was ease of servicing....as you can take out the board easily in case you want to replace parts...
Tony,
I used pre-packaged bridge rectifiers as well, mine are in a different package though.
Did you use anything between the "mounting bar" and the transistors to help disperse torque? I'm curious because I was going to do something similar to this idea. I'm still undecided on that for now.
Cheers,
Tim

as you can see i used an angle bar 10mm x 10mm x 2.5 mm so that torque should be evenly dispersed,
Over current protection can easily be added. How to build a 21st century protection board
Built in protection would be nice, especially for first time builders like myself.
This aside, I guess with all the different variants of badger's out there it would be hard to make a "one size fits all" protection without increasing the footprint significantly.
I plan on going the 21st century route myself, it's quite interesting/advanced set-up. I was reading the thread a year or two back, and it is a very impressive protection system.
