Help Identifying Components Please
« on: February 03, 2019, 04:16:00 pm »
Hello all,

I have a few components in my project amplifier that I can't seem to identify the values for, any help much appreciated!

Small clear Capacitor? Only markings are 39F and a feignt red band

All gray capacitors / resistors? marked EFM3 033Ohm 2%

Unmarked Output Transistors, tested with Multimeter Continuity setting and only get reading on the case / collector

Orange capacitor? marked 1K 100-130?

Thanks in advance.

Hello all,

I have a few components in my project amplifier that I can't seem to identify the values for, any help much appreciated!

Small clear Capacitor? Only markings are 39F and a feignt red band - 39 pF polystyrene

All gray capacitors / resistors? marked EFM3 033Ohm 2% - 0.33 ohm, 2 W resistors

Unmarked Output Transistors, tested with Multimeter Continuity setting and only get reading on the case / collector - no idea

Orange capacitor? marked 1K 100-130? - 1 nF polyester

Thanks in advance.

Either 33 or 0.33 Ohm, trust your multimeter.
