Where will I find a schematic with wattage values for all the resistors


Use this in Google to fine manuals and schematics:
Epiphone junior amplifier manual Google zoeken
Most resistors are 1/4 watt, unless something is added in the schematic.
You also can deduce the wastage, because for every size is a wattage, or the other way around.
When you are not sure, and it fits, use a bigger resistor. The same resistance (ohm) but a higher wattage is no problem as long as it fits in the housing.

Hello........ looking for a schematic for Bose 501 series 3 speakers. I need to replace the fuse in line with the tweeters.... its blown & does not have a value on it (unmarked, quick blow, twin lead,...


Did you find a solution? Dunno if it's much help, but I just today picked up some 501s - Series I I think - ugly heavy brown material grilles - but with a manual! No fuses in these, but booklet recommends installing your own in-line fuse holders (!?). Specifies a BUSS AGC-3 fuse for amps under 50wpc; or a MDL-2 fuse for amps over 50 wpc. Can be placed is series with either or the two signal wires. Very strange.... Robin

What is the cprimary load on a 12volt to 240 volt 300watt inverter


Ohm's law tells us that: volts = amps x resistance and watts =volts x amps. Watts (300) = volts (240) x Amps (?); or 300 / 240 = 1.25 Amps That means the inverter can supply up to 1.25 Amps to a 240 volt load.

The primary is 12 volts, this is just 1/20th of the secondary 240 volt output. Since the best you can ever get is 100% efficiency -this means you'll need to supply 20 times the current. 1.25 Amps (at 240V) x 20 = 25 Amps (at 12V). As a check, from above Ohm's law that states Watts=Volts X Amps we get: 12VDC x 25Amps = 300Watts. Check!

Some side notes. The Ohms law used above is for DC circuits and purely resistive loads on AC circuits. I do not know what your 1.25 A @ 240VAC load is - but I suspect it won't be purely resistive. Also, since we're working with an electronic inverter as opposed to a transformer and DC rectifier there are some things that push losses higher. You might need to provide a 30 Amp 12 VDC source voltage in order to provide the 1.25A @ 240VAC output. Lastly, I wouldn't not run the output at maximum for long periods of time - or at all. 1 Amp @ 240VAC would be much better.

I hope this answered your question & good luck! Please rate my reply - thank you.

What is the value of the resistor that burns up when to much RF power is input?


Hi wrightjc2,
Most common burned resistor are those with low resistance because it acts like a fuse to avoid further damaged to some parts if shorts,overload happened. But still best to have a schematic diagram to identify the burned one. If you haven't a schematic you may get the resistance of the resistor, measure it to the middle where the burned cut out, add the resistance from one half side to other half side. You may now have an Idea what may be the value of the burned resistor.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

PV Delta Blues. Resistor R-58. What's the value and wattage?


It appears to be a 430 ohm 5 Watt FLAMEPROOF resistor... The resistance value could also be 470 ohms...

Here is link to a 430 ohm:

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PPC5W430TB-ND

Here is link to schematic, however the resistance value is blurred but starts with 4 and is three digits leaving only 430 or 470 as the value:

Where can I get a schematic of the circuit board for the MG100DFX. The main fuse as blown and I need information on wiring connection to the transformer and values of other components.


Just a hint to troubleshoot: Connect a 100 Watt light bulb in series with the hot side of the power line into the amp. Make a cord with a light socket and a receptacle to plug the amp into. This acts as a resetable fuse and will send enough current through the amp to not fry stuff, but enough to do troubleshooting.
