Afternoon. i have a few old amps im stripping down and want to keep the 'good bits' for others i intend to repair.
original transformers are like gold dust for these so i dont want to ditch whats good.
Attached are 2 pics, one of the impedence switch on the back and one of the 4 board tappings to main fuses.
so these are the readings i got powered on, fuses removed on the board and i grounded to the transformer casing with it still connected to the amp casing.
impedence switch in 8 ohm setting
both orange connections 29vac
both blue connections 29vac
both red connections 25vac
impedence switch in 4 ohm setting
both orange connections 29vac
both blue connections 25vac
both red connections 25vac
so would this denote that this is ok?
second this is the connections to the main board where the fuses are (see pic)
these were taken again grounded to the transformer casing fuses removed.
oh and by the way this isnt my soldering on the switch, this is how i received it. 🙂
