Default OpAmp Heaven

I have a large quantity of operational amplifiers (AD797, AD825, AD622, LT1013, LT1014, etc. ), small signal transistors (like the hard to find MPS8599), MOSFETs, Lateral MOSFETs, high power On-Semi bipolars, voltage references (including the LM329DZ and TL431 in TO-92 and surface mount), ADC's DAC's, switching regulators, opto-devices (RGB to frequency converters!) , torroid cores, connectors etc. -- all the stuff that you and I use for audio DIY, ham-radio, photo-electronics, instrumentation, etc. Most of this stuff was bought through regular distributors in bulk, some was bought from "going-out-of-biz" sales in the great telecom bust. Shipping in the US is via priority mail at the rates described, and where available, to Europe, Africa, S. America and Asia via Global Priority Mail (if GPM isn't available, then Airmail Registry), PayPal is most preferred --

Hey, as the resident grump here, complaining is my job.

But, it's true - pretty sloppy site authoring.

It only looks dead. After clicking you have to scroll down.

I buy my matched L-MOSFETs here. Service is execellent even if the web site is awkward. Take another look and this time scroll down the page after clicking.

Hey you have an email! I am looking to build a 12VDC mono/stereo, 50-100W+ amp to show off at tailgate parties. Any kits/parts you may have to purchase I want.

Also: so what if he has a bad site, my site http://www.reubengathright.com has a horrible layout, but I am one of the recognized leaders in Dakota 4.7L tech information! If the guy is willing to help he is better than anyone IMO.

Default Hexfets

I have had many inquiries requesting matched sets of IRFP240 and IRF9610 so I changed the web-page to reflect pricing for these devices (in addition to IRFP240/9240 sets.)

I now have MJ15003 and MJ15004 back in stock -- also LR8N3 high voltage regulator chip from Supertex, and am busily matching IRF044's.

I have a couple of the Super Oscillator pcb's -- prototypes without silkscreen -- same as I described at http://www.tech-diy.com/TestEquipmen...oscillator.htm

there really isn't enough interest to make up a silk-screened board, but you can have a bare-board for $20 + shipping to CH-Land. Email me privately.

the Zetex filter chip is so obsolete that they don't even list it on their obsoleted product list -- I had someone interested in an analog spectrum analyzer based upon the chip:
