Impco J - no secondary test port :(

Post by jono » Sun Dec 10, 2017 11:23 pm

Anyone notice the J and its clones do not have a test port for the secondary chamber?

With such thin walls there really is no meat to add a 27 tip 1/8" taper hole and tap either

Maybe a larger rivnut/ nutsert inside out might do the trick?

If not possible it rules out using the J with Peel Instruments lean bias logic processor.

And you know, after kitting a J I think I prefer the L anyway
