Hi All,

got ML38S with Japanese voltage. I know it is switched by jumpers (apart from frequency detector). Apparently located underneath PCB, but it seems it is not possible to remove PCB without cutting XLR connectors, which are Switchcraft brand. I made full restoration of ML 27, ML23.5 but never had any 3x series on my bench. Is there any access to jumpers other then fully removing PCB, or if not - whether its possible to remove PB without cutting XLRs?

Arky,

I don't understand here. Looked at pictures of the 38 back panel and see NO power input connector. How does it get mains power?

All of the ML / Cello equipment I'm aware of had a readily accessible way to change the input voltage because when they were built. The actual customers line voltage was unknown at that time and had to be easily changed - NEVER by having to remove any connectors or PC board .
 
Hi. The power socket is standard IEC inlet and is located underneath the board. It is just in the middle of the bottom plate, connected by angle plug.

this is removed board, not mine unfortunately. In order to change voltage the whole board have to be removed. There are jumpers under the board at the connector P1002, you can see it in the middle. Connector is soldered, and it is put on those jumpers which are only acessible while the board is lifted. And apparently there's no access to the jumpers from the bottom of the device.
