These are great recivors I have bass mine for 30 years and it’s been faultless other than lamps and last time I used leds I use on my bench to power my real amp a crown DC300 a I love this things !
I saved one my neighbor was tossing. It was scratchy as hell, and speakers dropped in and out. He had it in his cellar shop. I opened it up and blew it out with my compressor. I also hit it with half a can of cleaner and worked the dials back and forth. It sounds great now. Only issues seem to be a little tuner drift, and a couple dial lights are out. Now it's my garage stereo.
Do you have advice for picking switches that will be exact replacements, or is it just a matter of having the same number of pins? Do you source them from the typical electronics warehouses? Thx for the informative videos!
Believe it or not, these same switches are being made today after 40+ years. They are a common form that can still be found at places like DigiKey and Mouser. The main consideration for substitution is will it physically fit and perform equal or better than the original. The number of pins is variable and switches come in all kinds of different configurations and pin numbers, depending on it's application. The hard part is finding the right switch for the job as there are thousands of different types out there
I thought there was more to it than just the pins, that’d be way too easy. I’ve had pretty good luck that I don’t have too many failed switches in my repairs, but I’ll have to learn more about how to match them if that ever comes up. Thx
I have this same receiver and have a similar tuning issue. Fuzzy when stereo light is on - which is rare and intermittent - making mono the better choice. Can you tell me what and where transistor you replaced? Thanks,
Do you recall what replacement part number you used for the signal strength meter? I just acquired an HK330C and the meter is dead. Would love to know what other part will work. Thanks for the great video. I love how you examine and think a lot before deciding what to do.
I don't have a part number. I used one from my supply that was the same physical size. Is the meter dead as in open or is it just stuck? If it's stuck you can back off on the bearings to free it up and make it work again Thanks
@@TrevorsBench Thanks Trevor. I'll try loosening it. I am ordering LED fuse lights and power supply capacitors and will wait for those before opening it up. Do you know what other capacitors in the signal path are important to replace? Thanks again for your great video!
@@bluesman608 How does your 330c sound right now? It should sound amazing if running properly. If it doesn't impress you after a few days of listening I would consider a full re-cap. Why I said a few days is because it takes time for caps to re-form and wake up if the receiver has been in a long slumber. The caps in the 330c are quality ELNA brand and rarely fail because none of them are heat stressed. If you want to do a full re-cap send me your email and I send back a excel spreadsheet that details all the values of caps needed.
@@TrevorsBench It sounds quite good, full and rich - much as I remember from my high school friend's HK430. There is a slight 60-Hz hum in the speakers. Maybe it's best to do the lights and let it be for now? Still, I would love to see the spreadsheet. Thank you so much for your help.
I have a 430 that needs freshened up. Has awful sound and no bass below ~50hZ. I figure it needs recapped. It's the worst sounding out of all of my HK units.
Most likely, you're right. The only things that really can go wrong are electrolytic caps and transistors. There are 4 capacitors in each channel amplifier signal path. One or more of these are probably dried up. If you change those your sound may come back. Of course, with out seeing it I'm guessing here and it could be something else
Everytime I see you with that razor blade I'm thinking he's going to slip and Nick his finger that's not a very good tool for using a real close to your finger like that
I don't know what you think about this but I'm going to let my opinion out you put videos out on teaching people of basically showing people how to how to fix irepair diagnosed Electronics and you have your comment section open does I believe people who put them out on TH-cam put any sort of video out on TH-cam should have their comment section open so they could have you know helpful criticism you know if somebody doesn't like something that you've done they should be able to voice their opinion and tell you what the hell do they think that you've done wrong and maybe it could help you do your videos better what I don't like is the people who put out videos and turn their comment sections off it's like they're cowards and they can't deal with criticism what is your thought on that
I want to hear your opinions. I'll admit, I'm not perfect at what I do and I'll make mistakes or do things that take 10x as long as they should. I'm a lousy teacher and I'm horrible at explaining things with words but maybe if I can show how I do things people will pick up on it or add to their knowledge. Or at least add to their confidence to try the repair themselves. I enjoy watching others do repair videos and learning their tricks or techniques. I don't believe that some people do things 'wrong' but rather have a different perspective and do things different. If the end result is success, it was done right even if the path to success was long and arduous. Also, people need to make mistakes. That's how we learn. Criticism is welcome here, insults are not.
Obviously, your keyboard is missing several keys, that would make your comment readable. I read it twice, and it's still hard to understand. How about some grammar, and that's not the opposite from grandpa.

Nice one. It's always good to hear these are being saved from the recycler/bin
Thanks for posting this video. Do you happen to have the part number for the replacement meter that you pieced together for the repair?

I would try an alignment first before suspecting transistors
I just snagged an HK PM655 on Ebay. I hope I don't have to ask you for repair. lol
Nice, let me know if you have troubles sorting it out

Seems the strange bulbs were replaced by LEDs? Is that a streight swap one to one or is there a modification needed?
I know this is two years later, but hi-fi audio sells a lamp kit for the 330 C, probably find them cheaper if you Google for them.
I work where they collect ewaste to be shredded many like it came in i asked if i could save it they said no
Yes, it's a crying shame these can't be saved

I've always said what doesn't kill you only makes you stronger, lol
red power light seems not repaired
strange first he has double sided sticky tape and later he glues it with hot glue.
