Thanks Norm

Yes. The chassis is 2.5" tall so no problems. Many of our original prototypes were turret board construction, but I prefer working with eyelets.

off topic, but just curious why do you prefer eyelets?

I was going to say "DYN-O_MITE" but you changed your avatar


thanks

These look good I will try them

BTW I use the RGP 30M diode and the sound difference between those and in4007's is very big. Just my two cents...

Jelle

What is the sound difference?

edit: I just realized these ar equivalent to the 307s

Looks to me like somebody should figure out why FREDs are good, figure out the current and voltage requirements, choose the best part. In other words, engineering. I am not going to get into the FRED good/bad argument. Although, if Randall Aiken uses something there is always good engineering behin...

Are those FRED's superior to: UF4007CT-ND ? Good point, the Fairchild's seem to be a favorite of many folks, and they are cheaper, even allowing that you may want to use more of them. They are faster, if it makes a difference. The others do have a 3 amp rating, which may make you feel good if you a...

Thanks, I get a PM every now and then from folks who bought a set of boards and can't figure them out, so I thought I'd help. The relay boards and the HRM should be pretty self explanatory, but if anyone needs them I can post them, just say the word. Hey Funk, these and any other board pics are hel...

I saw the Diode thing too. I updated the sheet so my order will reflect a couple of types

Diodes

FR307 583-FR307G 8 @0.82 total 6.56 3 amp FREDS like Randall Aiken uses

1N4007 75-515D350V47 10 @0.136 total 1.36 really need 7, but price break at 10

I'd really like to see this too.

I just got a set of Funk trannies & choke.

The look good and the specs are good. Plus, if I am not mistaken, the set has been proven a few times in Funk's own build. Hopefully I will hear how they sound soon.

How are the transformers coming?

Firstly Transformers, any other parts really - although I know I can source caps, pots and stuff from mouser, etc....

Does your amp have some different parts/values from the D'Lite? (sorry if this is redundant, I am new here)

If you want, or I can point you in the right place. Funk, either way is fine with me. I think I read somewhere you had some good ones, with plenty of heater current, good voltage and impedance taps, good steel. I am certainly not adverse to putting a few $$$ in your pocket for "R&D" costs - saves m...
