Heathkit T-4 Signal Tracer Repair and Upgrade (AmpMechanic

- In this AmpMechanic video, I decide to take a break from repairing amps in order to get my Heathkit T4 Signal Tracer working. This is will help me fix amps, radios, and other stuff a lot faster which means I will also be able to publish videos more quickly. In this video, I replace some capacitors and resistors and follow a recipe from Terry at D-Lab to fabricate a multisection electrolytic capacitor.
You did an outstanding job on this T4. I'm doing an IT-12 and just watched and got some great tips from your very informative video.
The noise function puts like 100 volts dc on the probe. You connect the probe to components and if they are noisy (ie. a fractured resistor) you will hear the noise. Can be used in circuit on tube equipment but not on solid state. Look into the dos and don'ts before you use it.
Awesome video! Thanks!
The Eico 147A came with a 1.5 watt 8 ohm 4" speaker. I changed it out to a 30 watt 8 ohm 4" Eminence. It makes some noise. Maybe 2 or 3 watts? Sounds like a mini Champ. Big thumbs up on the video and I hope to see this gem in action on your future videos!
Man I always wanted on of those old HK signal tracers. Lucky man! Good eye for the old gear. This old stuff works fantastic. Where do you sell your stuff? I am a new suscriber. Keep up the great videos.

Thank you for a great video.... I have question: I am replacing the Cap 50uF 150v. but I can only find 50uF 450v and the other one 20uF 350v do you think it will be fine with high voltage?
I have an Eico 147A Signal Tracer I've been playing guitar through for a while now but I still haven't figured out all the other mysterious uses for it yet. Vague instructions... But wouldn't it be cool to build a guitar amp that had all the signal tracer's capabilities built in?
