How can you tell if your opamp (opa 548 in a Gilmore power supply circuit) is oscillating if you only have basic (Fluke 177) DMM? Is there an easy test or measurement that would show such problems? I'd rather not test by listening to the output of an amp...

Just a heads up for those who could use these (PPA in particular): http://cgi.ebay.com/ws/eBayISAPI.dll...&category=4662

I could not figure this out. Is the Omron non-latching G6A DPDT relay http://oeiwcsnts1.omron.com/pdfcatal...df?OpenElement in a default setting when unpowered? That is, when unpowered, is the switch in a specified position?

I'm looking for a 100 V (or 64) 4700 uf electrolytic that is less than 1.75 inches (44.45 mm) tall. Can anyone recommend one that's easy to obtain in the US? It's for a power supply for the Gilmore dynamic. Thanks. -David

Hi all, I was hoping someone could help me here. I've been running my Gateway VX700 17" (Mitsubishi Diamondscan) monitor for a couple of years now at 1600X1200/72 Hz. All of a sudden, it makes a high pitched whine. The whine goes away if I lower the resolution. Any ideas whats happening? I...

What is Newark's philosophy? Charge the customer the highest shipping fee possible? I order 12 IC's and some transistors. Total weight an ounce at most. Total volume a few cubic inches. They ship it in a box that's about 2 1/2 feet long and 6 inches in both the other two dimensions (the IC's...

Hi all, I want to bypass the rectifier bride in my power supply (decouple?). The rect's are 100V/2 Amp, feed by aproximately 22V RMS AC. Can anyone tell me if the following caps are suitable? http://www.wima.com/fkp2.htm I was thinking of values around 500 nf. Any suggestions for...

In the schematic, R3 on the ground channel is listed as "inf". Is this "infinite"? Should a high value resistor go here. Also, just curious, why did the part labelling skip "R10".

Is +/- 15 volts safe to apply to this buffer?

I'm considering buying an Elpac wall wart to power my Meta. They seem to sell thier models in either a standard grade or a medical grade. Is the medical grade worth the additional price (aproximately twice as much as the standard)? In particular, would the medical grade be better at...

I don't know how many of you liked the Hyperion Cantos, but Simmons' new book "Ilium" is out. This looks like another epic tale- Ilium is part one of two. I'm about 60 pages into this and so far it looks very promising. Three tales are interwoven. Things are centered on the Greek gods...

Anyone try these? They have a buy one get one free deal. I usually smoke Marlboro lights, but was wondering how #27 compares.

My house ac wiring has some nasties coming out (hum, wierd warbling sounds). What is a cheap, effective way to eliminate it?

My Gilmore balanced dynamic is almost finished. It's actually a preamp, with crossfeed, 5 inputs, a tape loop, and four outputs. A tape loop output is provided on the front (one of the mini jacks). There is a balanced output on the front (the headphone jacks) and one on the back...

This heat sink is a beauty. Just replaced my Zalman flower with the slk 800. My cpu temps are 14 C lower. The fan clips work very nicely also. An excellent product.

Opinions anyone? How does it compare to T and T2? No spoilers please.

I just bought "Music for Airports", and I rather like it. Very soothing. Are Eno's other ambient works equally good? Any recomendations? The only other works of Eno'd I've heard are his albums with Fripp.

Can anyone recommend a nice 1/4" phone plug? One whose casing is as small as possible. If this were a perfect world, there would be one, with solder connections, the size of the beautiful 1/8" to 1/4" adapter supplied with the Senn 600's.

I tried to use my Alps Black Beauty 50K audio taper dual pot to attenuate the signal from a PCDP to my Senn 600's. It's only usefull during the first 1/3 and the last 1/3 of its rotation (the middle third doesn't change the level). Also, at the very end of its rotation, the signal to...

If I use an electrolytic capacitor to block DC from an amp's output, which way should it be wired? Does the polarity matter?

Hi all, If your looking for 2sa1015 and 2sc1815 transistors, check out http://www.suburban-elect.com/produc...SEMICONDUCTORS They have the 2sa1015 gr grade. I just ordered 160 of these. I'm not sure if they have the 1815 gr's, but you can call `em up and check. You can get the...

We've had several threads for the best album by prog-rock group x. But what's the best prog-rock album period? It's (of course), "Close to the Edge" by Yes.

Forgive the dumb question: When I have nothing connected to the inputs of my Gilmore Dynamic amp (no source, no pot), I get dc on the outputs of magnitude 18 volts. With a pot attached (or a source) to the inputs, the dc goes away. Is this normal? Does this have something to do with "input...

I was wondering if my unit is defective. Has anyone had a Sony D-E905 that momentarily throws out 1/2 volt DC from the line out when the unit is turned on and off?
