    Denon AVR 1804 amp won't switch on

    Sir bushtech . . . . . . . . . . . . . . Is your ICP-15 circuit protector the same as IC105 fuse? YES 3. 5.6V and 0.6V on base You seem to be interpreting that IC as being a transistor, that center leads diode is holding ground return of that IC up one diode junction voltage . . . .~600MV ...

    Marshall MA100C problem

    . Sir Blackwellefty . . . . . . Inspect and confirm: First how's about some info refresh, doesn't that unit use 4 larger power output EL34 tubes and 3 smaller support tubes and then the rest of its electronics is a mix-match of some 4 or so integrated circuits and the rest is transistors...

    Turning a flashing led circuit into solid? Pics inside

    . Sir Popeyethesailorman . . . . . . . . . .Bluto here . . . . . Here is a breakdown of what you are showing us. There is a wallwart transformer which supplies reduced line voltage to the board as shown on the pictorial markup. That feeds the 4 diodes on the board configured as a Full Wave...

    RF Choke Repair

    Kilo Echo . . . . . . . Victor Yankee . . .here . . . . You can see that the left end of that tri- wound choke goes to a ground lug and the right ends "stub" just appears to have experienced a metal fatigue break. Ohm from the chokes very left terminal to the wire "stub" to see if you...

    NPN Transistor Amp not working!!?!?!

    Sir ChristianMCA . . . . . . . You just are expecting WAAAAAAY-WAAAAAY more out of that WAAAAAY simplistic circuit than is being possible. The INPUT device probably has more power input capability than you could EVER expect to get out of this added amps end output. That 4.7 k collector...
