77 tach filter condenser
Can anyone recommend where it's possible to obtain the tach filter capacitor for a reasonable price? Paragon just raised their price to $50...and the best I've been able to find is about $30.... but I'm concerned with quality and customer service as well. Thanks for any suggestions.

Do a SEARCH on the Forum for "tach filter schematic". Then, take that to Radio Shack and tell them you want the (2) resistors and (2) capacitors shown in that schematic. Probably not much more than $10.
Empty the present canister; wrap/insulate or "pot" the new circuit and stuff it in the can. Good to go...

I am not sure Radio Shack still carries all of this but assuming the schematic posted in this forum is correct below are the correct parts from Mouser. In particular, the 100 pf mica cap (high stability) probably isn't available from Radio Shack.
I do a lot of vintage electronic restoration work and I have used Mouser as my primary supplier for years. They are very large and the service is excellent, they are part of TTI which is a Berkshire Hathaway company. When checking out if you want the cheapest shipping select USPS instead of the default UPS, of course if you want fast they have various UPS delivery options. There is no minimum order or handling fee.
The parts listed in the PDF attachment have the mouser part number and they are higher quality (higher voltage rating, more precise tolerance) than those listed on the schematic so they should be fine. Of course you are on your own for soldering

Most early 80's GM vehicles had a tach filter. Search eBay and other sources. I recall Year-One offered one around $30. Same for Ecklers, corvette America, Zip and others. $50 is out o' the question in this economy.
I bought my used replacement 'filter' for under $20 with shipping over 10 years ago but the prices should NOT have moved that much.
I even fabricated two (2) of my own before I found a used replacement. Funny, with a little ingenuity and parts from RadiosShack, you can make one for under $10 if you have patience, and can follow a diagram.

Corvette Central part number 663279
I was looking at getting this one for my Tach Filter to connect to the distributor side:
Corvette Central part number 663296
Anyone know if this is the correct application for a '76? Ours didn't come with a Tach Filter to reuse the connectors...
