Over the years we have developed a lot of of custom equipment ad
modifications for our own use and some of these have become popular
As an adjunct to some of the projects over the years we have made
parts and kits available to accompany them. This is not a profitable
endeavor and we don't really want to be in the parts business, but
we continue to make some of these available. Prices may be higher than
listed in the original article as our costs have risen.

no longer in production but we would be prepared to build more if
an order of sufficient quantity was placed.
Opamp Labs Kits (Unpublished)
- A kit exists to replace an Opamp Labs 425 amplifier with a modern
monolithic IC. It consists of only the PC board; the user will have
to provide resistors, decoupling capacitors, and an octal plug.
$5 each postpaid.
Kludge Spring (Popular Electronics, date unknown)

cluttering up the garage should anybody ever need one. $5/set of 4
Machine Oil (numerous tape machine maintenance articles)
- 2 oz of Royal Purple Synfilm 32. This is a synthetic oil that is
intended as a replacement for light machine oil, and can replace the
Mobil DTE or Castrol OC-11 light machine oils. It is more stable
and more pure than the original petroleum oils and is a more powerful
solvent. Recommended for use on Ampex 350 and 440 motor and pinch
roller bearings. Too thick for use on Ampex 440 scrape flutter idlers.
