Heathkit IP 18 Teardown & Full Rebuild

This Heathkit IP-18 gets all new wiring, caps, semiconductors and resistors, and gets it AC section completely reimagined and I'd like to think made a bit safer. Enjoy.

Friendly notice : The standard voltage in USA and canada is 120 Vac not 110Vac. This thrue for more than 50 years now. ( See NEC and canadian code CEC).

[@dtss_smudge]

I'll take your word regarding the NEC, but you got me curious. So I went back to the original manuals, and the specs for the IT-12 (dated 1962) called for 117VAC 50-60cps (!) and for the T-4 (dated 1958) was also 117 Vac 50-60 "cycle". Go figure.

...and I just realized you were commenting on the IP-18, not the T4/IT-12. The IP-18 (1968) called for "105 to 125 [assuming wired that way] 50-60 Hz" So it was more forgiving.

What is your ac safety power block device with the quick disconnect feature?

[@dtss_smudge]

Not 100% sure what you're referring to, but if you mean the 4-position white screw terminal block I use to wire the AC side, search Amazon for "terminal block white screw terminal". Not really quick disconnect, you have to loosen or tighten the terminal screws. Thanks for watching and leaving a comment!

@@dtss_smudge Sorry, I meant the ac mains connection box with the lift up covers, bigclive has one like that also, but I can not find one.
