Need schematic and/or service manual

Tone Meister , don;t know if this is any help in the interim but I found this

Info seem very scarce perhaps you could contact Demeter???

Here's my attempt to enlarge the tiny schematics remaining on that thread.

Yes, it does help. Have an issue in the power supply and was trying to ID the value of a 2W MO resistor which is shown as 47K on the schematic. Found some bad electrolytics on the PS board which likely took out that resistor.

Thanks OC!

I recently redrew the schematics for the Demeter VTMP-2a, having made some repairs & upgrades on one at my shop:
