Sony TC 800A portable R2R belts

[Trevor Leese]

Hi everyone, quick question for you all:
I need a set of belts for the Sony TC800A, will belts from a TC 800 or 800B fit the A model, these belts appear to be very hard to find but i can get them from the US but they are quoting the 800B in their reference.
Thanks in anticipation.
Trevor

Trevor,

Cannot easily see the difference between the TC-800/TC-800A/TC-800B models, can only guess that the drive belts probably are the same. Would be worth asking the USA seller as he may possibly know.

Yes I'll give it a try Dave, thanks.

Hi Maurice and thanks for the information, some kits appear to have 3 belts other 2 belts, my unit has 2 so that gave me cause to question 'will all belts fit all variations '.

Can i ask another question bud, the unit I have is an 800A uk model but the transformer inside says 110 volts 120 volts, the literature for the unit makes no mention of an external step up transformer so if I plug a 240 volts mains lead into the socket does the unit compensate automatically for this or is the model I've got purely built for the foreign market.

Hi Trevor,

A silly question maybe but how do you know it is UK, is it marked as UK/230/240 volts ?

Is there no sign of a 240 volt tapping on the transformer primary, is the mains wiring from the mains plug connected to the 110 or 120 volt primary tapping ?

Regards

If it turns out not to be a UK 230/240 model, then as Tony says in your other Thread you then would either need to power it from the 12 volt DC option or use a 240 to 110 volt mains adapter.

Hi David, i don't with all certainty know if it is a uk model, the unit came from a house clearance and an elderly chap owned it from new but thats as much as i know for definite.
Here is a photo of the transformer, it only shows 110 and 120 volts so I'd better not chance plugging it into 240 volt mains.

[Trevor Leese]

The issue really is that nowhere on the machine does it say what voltage the item is so unless you take the unit apart how would you know?
Here is a photo of the information plate on the underside of the deck, also have a read of the attached statement, does this means the voltage automatically adjusts or an I not understanding it correctly.

[DMcMahon]

Well Trevor unless there is a 240 volt tapping that I cannot see in the photo, it does look like this is 110 volt USA model. I assume the white wire going to the 110V tap goes to pin C of the mains connector as per the schematic.

Can only assume that previous UK owner used a step down mains adapter.

Okay David, thank you for your help mate. Its a conundrum given the info plate states nothing avout voltage.
Trevor

[DMcMahon]

I agree the information plate label is unhelpful in not stating the mains voltage requirements, does seem odd ?

To me there is nothing obvious in the other page that indicates that mains voltage is automatically adjusted, I consider you are reading it incorrectly.

[DMcMahon]

Meant to have added that the only Service manual/schematic I have seen for the TC-800 (no suffix stated) says on first page "For U.S.A." and in the spec sections lists 117V 60Hz as the power requirement in addition to the 12V DC option plus does not show a 240 tap on the transformer.

Which document did you find the statement in ?

[ms660]

According to the TC-800a service manual it's for 110, 120, 220 or 240 volts AC, 50/60Hz.

Also says the same in this document:

Well that is good Lawrence, where did you find the A version manual, does it show a 240 tapping or does it imply universal mains operation ?

Only read the voltage specs from a picture of the front of an A version manual on Google pics.

Also the Sony TC-800b is the same voltage specs (Doctsf)

It could be universal though I'm not totally sure, the OP would have to check properly.

Hi guys, thank you for all of your input, thoughts and advice, the top and bottom of it is that we can't be 100% sure, i too have the service manual from the US and as you state it does say on the front page that it is 117 volts but on the attached sheet it states all voltages.
So thanks anyway guys for taking the time and trouble to help out.

[ms660]

The manual implies it's universal for the mains, check all the transformer connections to make sure what's what for sure.
