RE: [beam] Best/Most Recent PSH schematic

What are the one or two nearest values you have available?

Subject: RE: [beam] Best/Most Recent PSH schematic

I have two questions.

1) I am building a SPSH from this site:
<http://bicoreeos.solarbotics.net/psh.html>
http://bicoreeos.solarbotics.net/psh.html and I do not have a 6.2M, 510K
or 8M resistors. Is there something about BEAM and uncommon resistor
values? When Radio Shack decided not to carry electronic components any
more and put there remaining stock on sale I bought out their entire
stock out and I still don't have the ones I need. Is there other
resistor values I can use? What is the tolerance of the values needed;
can I just use a value close to the one written without an effect on
performance?

2) This one is related to question 1. Is there a "package" I can buy
that has every resistor value from 1 to 10M? Being short a few
resistors when your almost done a freeforming a circuit is rather
annoying. This isn't the first time either.

Thanks.

PS: Anyone in the Ontario area want to throw 3 resistors in an envelope
and send them my way? ;^)
