VU Meter axial lamp bulb 8 volts 55 mA for Teac and Tascam and many other models pack of 2
I had great difficulty finding these as most Teac Tascam rails run just above 6 volts and even higher when a few bulbs have blown so for myself I managed to source an 8 volt Axial lamp with a body about 20mm long.
I was forced too buy a few hundred so have some over to sell on
You need to not cut the ends before soldering and I advise you to leave on if room there, when soldering them use a thin nose pair of pliers between the lamp and where you are soldering them, as that will shunt some of the heat away from the bulb
Nice old skool glow
