Hi,
When I turn this 1960's (?) Record Deck on, it gives a loud buzzing noise over the speakers. It increases with volume. I can plug my phone into the radio jack (and play music), and play a record on the deck, and the sound comes out, but there's always the loud buzzing noise.
I've got the speed changer, and turntable etc to work, and would like to get it cleaned up and fully working, as it could look lovely. However I don't have the electronic ability to fault find it. I do have the ability to use a multi-meter and do the odd bit of soldering etc, so would like to "have a go".
Does anyone think if I change the capacitors in the attached photos I may stand a chance of curing the buzzing noise? I don't want to throw a lot of money at it, or sub it out to someone (and have to pay them), and if it stands a decent chance, I'd like to give it a try.
I'm going to also put a copy of this post in the transistor amplifier section, as there may be a lot of experience there too.
Thanks, Rob

While I never owned this record deck I certainly recognise the capacitors in your photos as I repaired many 60,s radios with the same parts .
They were never high end especially that low voltage one in the first picture , I would start by changing them to a slightly higher value and voltage as I can guarantee that the ESR will be very high and the leakage will be large too.
I never liked those cheap capacitors although Hunts was a good company in low end products they didn't supply their best quality and after about 60 years they should be replaced.
I used to own a Hunts "capacitor checker " but it wasn't that accurate used a "magic eye " to null the bridge but it did have a neon for checking leakage in HV capacitors ----- change the capacitors first.
