Thanks. Never thought about the tap test on the protection relay before. Nice to learn a new thing. Cheers

I like the attention to detail Hitachi took on the circuit board bottom component labelling.

Thanks for the video. I hope you can find energy time and money to get your shop together the way you like. I don't have my hobby shop and it's really frustrating for me to not have my space and equipment to work on things. We get robbed of time and energy plus focus with disorganization.

Shango brought me to view your videos many years ago and I've learned many things from you. I appreciate what you do! Stay well.

Hey buddy…we really need to get you a desoldering station 😂
Good to see you posting regularly again.

Good video. Thank you so much.

Great repair Jordan!  🍻 Cheers from NC!

I enjoy the repairing Video Nice

I really learn a lot from your videos, and I appreciate that! Thanks!

What a dream to work on😊

A de solder station is nice when they’re working right. They’re a pain in the ass when they’re not working right. A good role of solder Wick works good all the time.

A great video. I prefer the early 1970's Hitachi receivers the best of Hitachi audio.. Hitachi built the Fisher 201, 202, and 203 for Fisher but Avery Fisher's engineers designed it. Another great sounding gem.

Another GREAT video...Thank You

A little tip for you.
Clean the relay (or any other switch) contacts with a q-tip and a little toothpaste. They are usually silver plated, so anything more abrasive is de
structive.

I went to the hobby store and found some sanding sticks by the cash in various grits. The sticks are 3 mm wide, 10 cm long and have a Styrofoam core. 3 for $2.50 CAD. I have found them quite useful for cleaning oxide off contacts in Dual turntables and relays. I am sure you can source them online.

I've seen a 1978 TV made by Salora that had not only reference points with voltage values or signal names, but even entire oscillographs silkscreened on the PCB. And a control LED for every power supply voltage. These TVs probably fix themselves.

I think hitachi engineered the first class g circuit.  The idea was adopted by pioneer for some of their integrated amps. Later refined and widely used by nad.  Also some proton units which used nad architecture.

A beautiful amp, but I'm a little biased have the SR604 since '79!

why can't... everybody do that.  WHAAAT??? and make it at all SERVICEABLE????🤣

Those pesky refusable resistors. Always drifting away.

@16:53 measuring the resistance in the pots.....look at your video. The first one you measured across the entire pot.....the second one measured across the wiper....
