Use a bulb tester (60/100 watt filamant bulb in series with mains) to identify unknown windings. It keeps you and the tranny safe and will let you measure the voltages.

The schematic shows a Power switch and a fuse, but it's on the scondary ![]() Besides that, post both a closeup picture and a hand drawn schematic of how the original transformer is connected, showing wire colors. Yes, Mooly's method is fine to measure ![]() Anyway I ask picture and schematic because Rage has been produced for many years, with some obvious variations, so yours might easily *not* match the posted schematic. |

OUCH !!!
Are you A 6.3 Ampere fuse in a *clearly* indicated 0.5A clip ![]() Well, besides that, you will need a 220V to 18+18V , 30 to 40 VA . Start searching. PS: probably irrelevant but I got curious: why are the pictures 4 years old? |

Yes

Just one stupid qestion for the pro's. Could you explain the (18+18V , 30 to 40 VA .) I am just starting to be an electronic mech. Greetz GatoPS: another pickture with the right date |

![]() I don't have one here, of course, but post #3 claims: Quote:
, I'll have to settle for second best, which is what somebody else posted.Your picture matches the one on post # 3 , and both show 3 secondary wires: two red ones (18 + 18V AC) and a red/yellow center tap. Neither yours nor # 3 matches *exactly* the schematic #3, which shows a single (red red) secondary with no center tap, and rectifies with a bridge (4 diodes connected in a "diamond" pattern). Yours used a Red/RY/R secondary and 2 rectifiers (the glass 1n4002 shown). Same end result by different means. And the 30 to 40 VA size comes from the circuitrequirements. By the way, Peavey itself prints "40W" (really 40 VA) as "power consumption", so, who am I to disagree? ![]() If you want to measure your transformer (recommended), set your multimeter to the 200VAC scale , touch ground (chassis) with black probe, measure with red probe touching red wires. With the amp on, of course. I guess you are now using a 220/110V transformer to make the amp work. Post results. |

Yes thats correct I use a 220 to 110v to use the amp.
I want to thank you for the patience and the info that you gave me and I will go and try to get a proper transformer for my peavey rage 108. I will keep you up to dat. Thanks again and keep up the static (haha just joking) ![]() ![]() And
