Beeblebrox Posted January 13, 2023 Share Posted January 13, 2023 (edited) I am in the market for an internal speaker for my 800 which is missing. I know it's more or less only used for keyclicks and a few rudametary sounds, but I'd like to get one nonetheless. Anyone know the spec and also a modern (cheap) UK source for one? So a modern replacement for this: https://www.ebay.co.uk/itm/133063072388 I can make up a connector but just need to know the tech spec, dimensions, etc so I can either search for a replacement, go with a speaker supplier in the UK anyone may recommend, etc. I think it's likely I'll be able to get something cheap from Ebay or Amazon once I know what to search for. Had a quick look on AA and Googled but without a spec I'm just guessing. I can by a NoS one from the States on Ebnay but obviously not worth it after shipping/fees. thanks in advance Edited January 13, 2023 by Beeblebrox Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted January 13, 2023 Share Posted January 13, 2023 Have a look on the back, it's probably (hopefully) a bog standard 8 ohm speaker in which case anything that's the right dimension will do the job. Quote Link to comment Share on other sites More sharing options...

Oops!!!, thought you might open up one of your 800's for a look (assume you have one), if not, I'll open mine up and check for you Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted January 13, 2023 Author Share Posted January 13, 2023 @TGB1718 Nope, my 800 doesn't have a speaker to look Many thanks for poppin the hood to have a look Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted January 13, 2023 Share Posted January 13, 2023 Here's a photo, had to try remove all the "sponge gunk" off the back. It's a 63 Ohm 2 1/4" speaker with a 100 Ohm resistor on each terminal. Quote Link to comment Share on other sites More sharing options...

Beeblebrox Posted January 13, 2023 Author Share Posted January 13, 2023 (edited) @TGB1718 So a quick search on Ebay: https://www.ebay.co.uk/itm/204210280880?h This one is slightly bigger in diameter and is 64ohm. Compatible? Edited January 13, 2023 by Beeblebrox Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted January 13, 2023 Share Posted January 13, 2023 As long as it will fit in the case it will do nicely, don't forget the 100 Ohm resistors in series on each terminal Quote Link to comment Share on other sites More sharing options...

Thanks for the resistor tip. I'll put a bid on the listing. Now I need to source the 2 pin connector. Any chance you happen to know what it is called? I can rig something up no problems but if they are dirt cheap I may as well source them. Thanks Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted January 13, 2023 Share Posted January 13, 2023 Sorry, I have no idea what it's called Quote Link to comment Share on other sites More sharing options...

bandit Posted January 13, 2023 Share Posted January 13, 2023 Yes, Then you can Listen to the Stereo Player for the 800 from back in 80's which use the internal speaker. 2 Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted January 14, 2023 Author Share Posted January 14, 2023 So I managed to secure tbe following little speakers as well: https://www.ebay.co.uk/itm/255421668280 5 x 64 Ohm Miniature Mylar Cone 0.25W Speaker 50mm x 16mm And I figured I could use one of these for making a connector : https://www.ebay.co.uk/itm/384307473995 It is likely the back of the speaker is too large in diameter to sit in the original recess in the 800's casing so I'll probably just stick it to the inside of the case with a sticky fixer pad.

Peri Noid Posted January 14, 2023 Share Posted January 14, 2023 Good that this topic exists. I need a speaker for my 400 so I'll use the information from this topic :-) Now, where to find such a speaker somewhere near... :-) Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted January 18, 2023 Author Share Posted January 18, 2023 Little update and question. The 5x pack of speakers arrived but the seem to have strong magnets on the back. I am a little reluctant to use them inside my 800. Any idea if I am being over cautious? I know magnetic fields are no good for magntic media obviously. What about ICs and also signal interference?

Might not be the best idea to sit the 800 directly on top of a TV / monitor, but I don't see that as being an issue. 1 Quote Link to comment Share on other sites More sharing options...

Beeblebrox Posted January 29, 2023 Author Share Posted January 29, 2023 (edited) Just a little update. I assembled the speaker and it works well. Went with the 63mm 64ohm in the end. 100omh resistors on each wire and the small automotive plastic electrics connector is a perfect fit. Because of the the slightly larger diameter speaker and bigger profile the lower casing prongs won't alow the casing to close without piercing the speaker. So I taped the speaker to the upper casing just below the vents. All good. Edited January 29, 2023 by Beeblebrox Quote Link to comment Share on other sites More sharing options...
