Tube radio / phono restoration - anyone done it?

[Strychnine]

Im the new owner of an old Emud 923 radio and I really want this thing working 100% again; especially the phonograph. It was made in Western Germany most likely in the '50s.

There's a horrible hum that drowns out nearly everything, and I don't know dick about old tube stuff.

Does anyone here have experience w old electronics or know of a good resource?

first, change all those capacitors, those can looking things next to the tubes, they cause the bad buzz or hum

capacitors are what is causing the hum..The tubes rarely go bad

Nice looking piece! My dad brought me an old radio cabinet. I am almost done refinishing it. I wish it still had the internals.

I've got an old Grundig in storage that does shortwave too, that's a cool looking project!

Bumping this for a new question.

I'd like to put new speakers in this, and add new hardware to make it Bluetooth capable, but also keep the record player functional.

Anyone good with this stuff and want to let me pick their brain?

Have you tried turning it off and then back on again?

Do wifi instead of Bluetooth. Better sound quality.

I'm retarded, slow down and speak loudly.

If I do that, can I still send podcasts and things from my phone to it, or does that basically turn it into one of these new EchoDot things?

insert bluetooth speaker, done!

They make adapter circuits to make this happen. I was looking into it when I was trying to get my old stereo cabinet functional after I got done refinishing it. I'll see if I can dig up some links

Here is something I found through a quick search. There is usually some pretty good info on that board

Speakers are more than likely 8 ohm and can be changed out... BUT make be careful of the size of the magnet. These old radios were very low output wattage and require speakers to match. Most modern speakers are all about how many decibel they can produce and therefore a lot more input wattage to drive them. Check the minimum amplifier input spec before buying. You want some in the 1 watt to 4 watt range.

I am trying to figure out how I can get 5+ speakers wirelessly connected to the same audio simultaneously. Before someone says "Sonos", this is something I want to do at home and not spend $3000 on.

Bluetooth is great if you want to connect two devices, but falls way short if you want to do anything more than that.

What I really want is a master 'distributor' device that accepts any number of inputs (analog and digital, records/CDs/laptop/TV, etc), and broadcasts the signal out to all the speakers. That seems like it would be easy to find but I haven't had any luck. It's been about a year since I looked.

This is my 1957 Garrard record player with corner satellite speakers.
