OUTPUT TRANSISTOR STEREO RECEIVER / AMPLIFIER CROSS-REFERENCE CHART

Transistor Cross-Reference chart showing stereo receiver / amplifier models that use the same original / OEM output transistors / semiconductors. We will be adding more units as time allows. We may add more 'electronic parts cross-references, for items such as IC chips and relays in the future.
To 'search' / 'find' an occurrence of a part number / model number, or any text, using 'Internet Explorer' simply mouse over 'Edit' in the upper left of the tool bar at the top of your screen, and select 'Find...' or 'Find on this Page', type in 'EXACTLY what you are looking for into the 'Find What' field and press 'Find Next'.

The information on this page is from deduced from what we have found while servicing units. While most units that come through our shop will have their original / OEM devices, occasionally we will find substitutions in them. If they are 'known aftermarket' parts made by ECG, STK, NTE etc. then we list them as probably 'replacements'. A service shop may have substituted a 'Toshiba' for an 'NEC' or 'Motorola' or some other brand that could have come in a comparable unit originally. In that case, we will likely list them. Also, manufacturers changed device suppliers from time to time, without any notice or notation in a service manual or addendum, simply because one device mfg discontinued a component / semiconductor, or the equipment mfg may have gotten a better price from another supplier on another brand.
These are not necessarily parts we have available or for sale, nor do we know who does. This information is only posted for reference purposes.

 

 
 

We will be listing MANY more units as time allows.
