Really interesting , I owned one of theses back in the 70's and I was thinking of getting another , at 73 I'm a bit too old to learn what you know entirely but I'm experienced enough to possibly follow and with a few more viewings of similar video's I could have a go at setting one up plus some others in time . I'm curious to know (as I don't remember) do they use a LED or filament for the 'ON' light ? Somehow I don't think so tho!
It is very likely that the amp is designed to run on 117V AC mains, being that it is that old. And now if you run it at 120V - 125V the secondaries will increase as well. I would replace all caps that are 50V with 63V and i would increase the main filter cap capacitance as well for a bit of boost in dynamic performance.
Thanks for another great video. Question about your Capacity Wizard. Did you find this works better than other in circuit testers such as peaks or is just the one you all ways used. Looking to buy my first in circuit cap tester.
@@VintageAudioFever definitely will improve in sound quality. I don't know what is the value of the filter capacitor after the rectifier bridge but I will definitely put in at list 10000uf and on the output capacitors 4700uf
@@VintageAudioFever (TK-350) its for sale in the uk. so probably not worth it for you because of postage. but very heavy, has germanium detector diodes possibly germanium transistors too, Trio gear was well built. good video, thank you.

Nice work and a nice amp. More than enough wattage to fill a room with great sound.
Could you please tell me what code transistor the kenwood 402 runs?

that makes alot of sense....thank you!!

I really enjoy this cpacitor wizard, it will test great in circuit but remember, it only test ESR, not value.
I will definitely change the filter capacitor and I will go with higher capacity to smooth better the ripple and also the output capacitors as well!
Yes...that would certainly been a possibility.

Cute little amp with good power. Joe how about a video tour of your shop.
Good idea!
i currently have the tuner that goes with this amp for sale on ebay
ok cool...I might be interested... whats the tuner model number?

ഹായ് സുഖമാണോ?
I'm good....how are you?
@@VintageAudioFever I'm fine
40 watts ... that amp wont even be able to power my speakers even my pc speakers have more power then that
