IBM 5110 transformer?

Is it a switcher or an AC? A custom transformer is going to be quite expensive. About the only way is to cannibalize another machine.

A friend of mine is trying to repair a IBM 5110. He is convinced that the transformer is bad. Anyone knows the spec of the transformer? Someone that has a spare? Looking into the tech documentation tell me that the machine requires +/- 5V and +/- 12 V and also +8.5V A very rough guesstimate based on the number of wires from the PSU to the backplane would give 20A 5V, 4A +12V, 4A +8.5V, 1A -5V and 1A -12V. Anyone with a better guess? /Mattis
