Heresy I terminal replacement


cheeseholidays

Recommended Posts

Hello all, I’m wanting to swap out the terminals on my mid-70s Heresy I (long story short the heads of a couple of the terminal screws have broken off leaving the stem behind).

 

I ordered a pair of replacement terminals (Cinch 2-142 - appears to be a match) and I have everything I need to do the work, but I have two questions:

 

1. What’s the best way to gain entry to the cabinet? I poked around and removed the rear screws on one, but it didn’t seem “ready” to come off - I didn’t want to cause damage so I didn’t continue.

 

2. Is there anything else I should look to do to them while I have them open?

 

Thanks!

PS I would replace with 6 or 8 screw connectors and use the outside two

the leads on the inside are dangerously close.

I think the OP is having difficulty getting the back panel off after removing the screws. I would rap on the back panel with a rubber mallet to hopefully free up

whatever is causing the back panel to stick.

Correct, yeah. I just didn’t want to force it. If those screws are all there is, I have a rubber mallet and can try coaxing it a bit. Felt like a bad idea to blindly start trying to pry it off.

 

Regarding the terminals, I unfortunately had already ordered the two terminal version. Mouser already shipped it too, so I will probably use those at least for now.

remove all screws , take a   wide metal scraper , lodge it gently into the   corners and the center top-bottom / sides   ,   pull out very gently until there is a gap ,  the 1/2 inch  rear wood panel will come loose ,   slow and easy does it   .

I replaced the terminals in some of my Heresies with terminal cups.  Round are trivial to cut, install and seal.

I like this solution, but if you do not want to cut the back, something like this will work nicely.  Might need to make the drill holes a little larger.
