The value of output transistor of europower ep 2500 amp

Hi,
if it is enough you can get the schematic diagram of this amplifier.
Thanks.

There was an suggested solution here for your problem.

There are electronic components which seems to be undiscoverable

for a moment.


• The fault could be anywhere from the differential input stage

to the VAS circuits.

• One has to check thoroughly components , and proceed

troubleshooting without the power transistors connected.


• Check for offset voltage on each of the main amp output.

• Check for idling current


A good amp never produce an over of 0.7V on its output.

Absolutly, I serviced amps for years and prefer a vac and dry brush over compressed air that can blow dust into controls.
Cheers,

You can do that but your subs will have to be monsters or you will blow them out as bridged mode will drive 2400 watts RMS into 4 ohms. Many speakers are rated in peak or program power... these are FAKE specifications. with this amp in bridged mode each of two identical speakers would have to be rated at 2400 watts program or about 3600 watts peak each to survive... When rating speakers and amps ALWAYS compare RMS values... and for safety use an amp of 80% of the RMS rating of the connected speaker or speaker system.

Paragraph 2.3 shows the DIP switches and what they do.

This unit has the following output specs:

2 x 1200W into 2 Ohms (stereo)

2400W into 4 ohms bridge mode (mono)

DISCONNECT ALL INPUTS(MIC CD) AND CHECK.DISCONNECT ALL OUTPUTS AND CHECK(ALL SPEAKERS ONE BY ONE)IF THE PROBLEM CLEARED WHEN YOU DISCONNECT ANY INPUT OR OUTPUT FIX IT BY CHANGING START WITH CABLES FIRST.

Faichild/Toshiba make the output transistors for the ep2500, part numbers 2SA1943 and the 2SC5200. Beware though there are a lot of dodgy fakes around on ebay. Profusion are excellent. Heres the links for them.

if after the pop it smells like a firecracker just went of than you fried the circit for that speaker or if it has fuses on it or ferther down the wire check them but it could be just the radio and nothin to worry about:)  a friends car does it, and it is very anoying

Probably the power amp has arced and popped a lot of components.

When teh amps go usually the final pwer transistors, their drivers and sometimes even the power supply gets zapped.

Check the output of the preamp at the inserts for the final amp with headphones to see if anything is coming through.
