Yamaha receiver model:RX-V1070

Yamaha home receiver (amp) model:RX-V1070,year:1996 (guess),no power or
display only relay click.Found the the right channel parts defective:

2SA1302=NTE2329
2SC3281=NTE2328
Q139=2SA1145=NTE32
Q136=2SC2705=NTE31
R225=0.22 ohm,5 watt,dual emitter resistor

I need the values for these:

R223= (guessing it's 760 ohms,1/4 w)
R201= (guessing it's 922 ohms,1/4 w)
R202= (guessing it's 920 ohms,1/4 w)

as the other channels pcb layout is similar but confusing and the part

R223 = 4.7 Kohms
R201 = 1 Kohm
R202 = 330 ohms

Beware of phony transistors. The 2SC3281 and 2SA1302 are no longer made. NTE
has also been reported as supplying fakes.

The modern equivalents are 2SC5200 and 2SA1943.

In the US a company called B & D Enterprises supplies top-quality original
transistors.

Google "Bdent.com"

The display backlight lamp may also be bad, that was quite common on these.

Are they fuseable,metal film or metal oxide? also Mark do you have any
info on the lamp?.Thanks.

Most Yamaha lamps are 14 volts. I just read the resistor values from the
schematic - it didn't say whether fusible, though I'm sure it specifies
carbon or whichever in the parts list.

Yamaha's positon is to replace them with flameproof (fusible) types.
Absolutely do not replace fusible types with carbon, anyway.

If the originals really burned they were carbon.
