rowe r-88 battery
i picked up a rowe 88 jukebox the other day. was supose to be working but as usual people have different ideas ona working jukebox. i checked the battery and it has some corrosion on it. i removed the battery but dont know what voltage it is so i can replace it. i have a r-86 manual but it doesnt say anything about the battery. when i turn the machine on it selects a record and keeps doing so. if i clear the memory then it works fairly well. as it also has a sound volume problem but wanted to get the think working right first. it has a bad service switch on it but i managed to get it together and with a help of a jumper as told here i managed to get it to power up okay although im looking for a service switch for it. i want to put a remote battery on it so can someone help me with the voltage. thanks norm

One will have a lithium battery at the right about the size of a 20c coin. These are typically 3 - 3.6v coin cells and are not rechargeable. You can replace with a similar lithium coin cell, or a 1/2AA size lithium battery with solder leads on it. These should last for a decade easily The older type board has the battery a bit to the right of the centre, and it will either be a black plastic box about the size of an AA battery. This POS is a Nicad battery, and these are guaranteed to leak within a few years of being installed. These are charged by the board when the mains is on. In cases like this - DO NOT put the same thing back in or you will get more future corrosion. When I operated these machines years back, we used a 1F supercap which never gave any problems with memory loss. This is an "install and forget" job. You could use a lithium battery here also, but you must remove the charging resistor, and for this you need to know what you are doing. If you want to go this way, reply here with details of which board you have and I will dig out some manuals |

The battery that you require is a 2.4 Varta battery on some of the R-84 to R-88 boards it is a direct replacement, just unsolder and put a new one in on the earler boards it had an oblong battery so the board needs to be drilled to accept the battery negative pin, only use one of the positive pins. The battery is the rechargeable type. On the R-89 to R-94 CCC they use a 3 volt button type cell that is soldered to the board. Regards Alan Hood ami-man UK |

Regards Alan Hood ami-man UK -- Alan Hood I did own an R-88 which had the R-89-94 type board and later amp factory fitted, so it is likely there are others out there like this too. The board layout was slightly different though from the later model (computer memory, ROM ? etc was wired to a different address IIRC, so it couldnt be converted to CD combo, with a ROM change), probably because of the single rather than dual display used. The display also had extra LEDS to show what function was being displayed at the time, had larger LED displays than earlier models, while the same sized board and assembly was electrically totally different to the R-86 and before. |
