Hi Mark,
it's not a mallet you'll need, it's one heck of a whip to get me going that quickly.

Hey Bikehorn... I need your shipping address!!!

Thanks.... Mark

Very nice boards Mark.

In the past there was also the idea to add the resistor package to the GB. Maybe i didnot read all the post about this topic. Cannot find it in the WIKI.
Are there still plans to do this?
Thanks,Loek

Mark A. Gulbrandsen · 29th January 2007, 03:12 PM

At this point there are no plans for any other parts package. The only uncommon part is the 1N5309 current limiting diode so all parts should be very easy to aquire.

Mouser shows 600+ 1N5309 in stock.

True but if you check DigiKey and Mouser's ridiculous overseas shipping charges you'll understand non-US builders' chagrin

But yeah Mark's right, everything else is pretty easy to source from most vendors. The original used Dale 0.5W resistors which can be bought from Welborne labs. No real point in going more expensive, and since they're not so expensive worth it over generic metal films.

The 100nF's were Roederstein axial films, and the pF values (680, 62, 20) were all silvered mica, all stocked by Parts Connexion at $0.75 each but polystyrene will do nicely too, just check if it'll fit on the board. For the 1000uF feedback cap use something nice, but check for low ESL - no point in low ESR since the cap is in series with 825ohms anyway

I would be happy to do a 1N5309 group buy but not a whole parts order buy... I just don't have the time. I'd also be happy to be a second party shipper one at a time so none of you have to pay those rediclous shipping charges.

Indeed, and regular suppliers don't sell the 1N5309 overhere.
The J509 is also not on stock, so if the currentregulator diode could be added would be nice. I am not in a hurry to receive the boards....
I will try to get samples from Vishay.
Thanks, Loek

Is the 1N5309 superior to the J509? There sure is a difference in price at Mouser.

I got my boards. Really, really, really nice work.
Thank you Mark
