My dad just gave his that he bought in Okinawa while in the military. It was working great and until it started smoking. This is super helpful with restoring/repairing it.

Thank you for your time on this unicorn! When I started my first full-time job in late 1978, my then supervisor had one of these and 2 pair of HPM-100's. Talk about a beast, these are like hen's teeth nowadays; especially in really nice condition. The slight surface & paint corrosion damage can easily be repaired; your customer will be more than pleased when this restoration is complete. Really looking forward to the next video of the amplifier section...enjoy your weekend!

Hi Trevor, I've found a tiny ball of blue tack pushed into the switch hole before mounting on to the switch shaft to be a great option.. The blue tack finds it's own places to grip inside the switch knob and it's not permanent..

Thanks for the 1000hz warning. My wife is not a fan and lets me know it. Xray tony keeps a lager trigger operated iron for large heat sinks when desoldering. Brave move with the torch around the tuner cord. I use an eye dropper on the grounds on the tuner to avoid spraying the fins.

A Wen or Weller soldering gun would make quick work of the solder points on the tuning capacitor box. Most of my work is with the older tube rigs and I've used both of these guns for many years. However, a Weller iron is used with printed circuit boards.

SO RIGHT!!! When he got out his TORCH for unsoldering I nearly fell off my chair.... It will do the job, but it definitely needs to be in the hands of a Skilled Knowledgeable Technician, and he is definitely that person!!!

I only recently discovered your channel and I'm catching up a bit on some of your videos. Really enjoying them and loving your work so far! In this video and some others I've seen, I heard you mention a list of bad transistors which you always swap. Could you share that list and how you compiled it? Excellent job on this receiver, by the way!

The list I keep talking about came from the AudioKarma forum. Search there for "top ten worst transistors" or something like that. Credit goes to Dlucy and other contributors of the forum, not myself

did not see the video but good video again!!! REAL REPAIR VIDEO, hands on not this theory math crap. AWESOME BEST CHANNEL EVER and you are so nice and staight forward, really refreshing. Not as good as harman/kardon but still a nice unit. PS: You should not touch the big capacitors like that, they may can zap you. They look dangerously huge.

Could that stuff that leaked from the Elna caps be some kind of sealant that has leaked out during production? Like when they were soldered to the PCB? Didn't look like it did any damage to the PCB...

On the phono bored where you had the dual tantalum 0.47 microfarad capacitors in series, that would be . 235 microfarad. You stated that you put a 2.2 microfarad film capacitor in as a replacement. Just wondering if you meant .22 microfarad film capacitor? I was also wondering about that large yellow .047 microfarad film cap near the rear of the chassis?

I understand parallel and series cap math. I went back and reviewed the video and I had definitely misheard what you said Trevor about the value. All is well in River City. 😁 Ears are not what they once were. Sorry for the churn. I am still curious about what that large .047 microfarad cap was for in the rear of the chassis. Thanks for the videos, especially on these mid to late '70 beasts!
