That's right. We get 500-1000 emails a day -- April was even more than that. Heinz-W. Schockenbaum wrote:

Re: is there a model or subckt for the PWM chip SG3524?
Hi Gandolf. First pass, yer parts count has just gone way way WAY down. Check your folder for the "rs-01" mods. I left the holes where the old parts were and added jumpers to show where the new

Re: Kevin -- Tip: a cheap full load resistor
It will be unmoderated. Will you be available to be a second owner in case something happens to me so it can be shut down if it gets out of control (trolls, spam, etc.)? Helmut wrote:

Re: dual npn transistors and some obsolete op-amps
Usually a netlist is relatively easy to convert to a subcircuit. Send me the netlist and I'll see if I can convert it.

Re: dual npn transistors and some obsolete op-amps
I also tried searching for it, and you were right, it was the first one on the search list.. sorry about that.. but uhhm, how do you convert that information to a spice model?

What do you mean? Do you have the LTSPICE model of 2n2920?? If so, could you post here. It would be very helpful.
