VRX-9000 (Protector LED)

Submitted by Ogre1 on June 21st, 2018.

I recently received this receiver from my father-in-law. It's been sitting in his garage for the last 10+ years, and worked fine when he retired it to the shelf.

When I turn it on, all of the lights come on, but the PROTECTOR LED never goes off.

I've got it connected to a pair of Cerwin Vega D1 speakers that work fine connected to my Onkyo amp.

I don't have the Operations Manual, so I'm unsure whether I have something connected wrong, or switches set incorrectly.

Any suggestions, or do I need to find a service tech to give it a good cleaning and text things out?

Vector Research VA 1450 transformers

Submitted by steinkare on November 27th, 2017.

I have a pair of transformer from a Vector Research VA 1450 power amp. the plan was to use them in a power supply for a poweramp I am building.There are four wires on the primary side of the transformer and I am going to connect them to 230v.
How do I connect these wire? There are one
white, an orange, a blue and a one brown wire on the primary side. Its probably two of these wires that should be connected together and the two others should be connected to 230v.
