Krell KSA 100mkII Clone

"I have looked at adding a two transistor CCS to the PCB but it's going to look messy, even piggy back fashion.
If I add a few components to stiffen the CCS rail supply and clean up any rail modualtion then the one component 1n5309/509 becomes ten components, even messier. "

Andrew,
This wouldn't look so bad if a small board were done to allow it to be connected to the back of the existing board. Could you please post your design so I could try it???

Thanks,
Mark
 
Also.... I am going to order 1N5309's for some overseas people so if any of you other overseas folks want them at a savings please let me know by Tommrrow Night!!!

Price would be $4.29 USD each(so at least you get the 25 up pricing) plus $9.95 Global Priority Mail shipping. Domestic folks welcome too but shipping is just $4.95 Payment needs to be via PayPal.

I am heading out of town on a service trip for 10 days so this order will go in before I leave this Monday and will be shipped out as soon as I get back in town.

Just e-mail me at cinerama84106 at yahoo.com

I hope I'm not too late. I'd like to order 5 of those (4 and one spare).
(I'm not totally up to date on this, but it's two per board, isn't it?)
I'm in the UK.

Regards
P.S: Lovely boards! Got them yesterday from Steen.

So it be $4.29 x 4 = $17.16 for stereo
S&H handling $4.95
total cost = $22.11 ???


If this is correct, count me in...

Hi Mark,
I will take the four gold plated boards and 1N5309's.
I will send you an email.

Thanks
Harry
 
Hi Mark,
here's the two BJT CCS.
R5 is a dummy load to represent the FET LTP.
The resistor values are set up for +Vrail=+52Vdc and Zener=20V, 400mW.
The other CCS will use a PNP pair and the polarised components are reversed.

To all,
What repercussions are there with using the 22uF electrolytic?

Is there any advantage to swapping out R1=220r and replacing with 270r//2kpot to allow accurate setting of the LTP tail currents?

Here is the list so far of those wanting 1N5309's. We are at 85 so far..... If we get to 100 the price goes down a tuny bit more to 3.99 each. The list as I have figured it so far is below. If I have left your name off or have the quantity wrong it is just by accident so please let me know.

Thanks,
Mark
