This is a "portable" record player from around 1963. The speakers open and the turntable pulls down. The speakers are connected to the amp via their metal hinges to the cabinet, and buzz badly. There seem to be 13 tubes (12AX7=ECC83 type) and some metal square prisms in between the tubes (?). They buzz whether the tuner or the record player is on. Any ideas how to stop this buzz? It seems like I could replace some tubes but I dont know how to tell which to replace. Any info on this thing would be great!

I haven't seen a Garrard record player for a long time. A buzz is normally not a tube. It is more likely a capacitor that has gone bad, possibly in the plate power supply. It would be very difficult for someone that is not knowledgeable in electronics to fix it. From a practical standpoint, it may not be worth fixing. If it means something to you from a sentimental point it would be worth taking it into a shop to see what they would have to say.

more than likely a power cap. They dry out after 40 years.
may be hard to find exact replacement. But u can probably fit an equivalent. Make sure the voltage is => the one there.
The capacitance can vary +- 20%
the best advice it to go ahead and replace ALL electrolytics.
u may still have an issue after that, but tubes don't go bad sitting around, but they do go bad and may be a challenge to find replacements. The ones in that are probably fairly common thought. Good old 12AU7s.
If u are handy, it will be the biggest one(s) there.
it may be paper or it may be a can mounted on the chassis.
It may also be a multi unit device - more than 2 wires.
don't get confused.
It may also be a bad ground.

No. I tell lies to my purchasers every time i bypass to artwork, infront of my colleagues and with the certainty and approval of my boss. in case you disapprove then you definitely tell me a thank you to calm an 80 4 3 hundred and sixty 5 days previous widow who's hysterical approximately getting abode because of the fact she had slightly one the day previous to this and her husband does not be responsive to a thank you to look after it. My reaction to her is that she is staying with us to get well, she would have the capacity to no longer be any good to the newborn if she is going abode and collapses and that i've got sent a nurse to assist her husband.
