    i bought a Technics Model Number SA-8500X Quad Reciever & am trying to locate the Grain of Wheat Bulbs I bought some & they are all to Dim. So what went wrong? How do I find the Original ones like the Sechmatic says?

    PL1 thru PL10 is 6.3 volts at .25 amp (250ma) and PL11 is 6.3 volts at 70ma (likely an indicator light). Problem is no one makes or has stock for 250ma grain of wheat. LED is an option. You need a diode and voltage dropping resistor for each LED

    BTW- available grain of wheat bulbs like you bought are only 70 ma. The higher the ma rating, the brighter the bulb.

    I bought this off of EBay 2 month’s ago & the Seller took me to the woodshed on the Reciever. I never in my life thought I’d have to replace all this listed below. 1st it took me 1 Week with Qtips to clean the whole inside out. I had to Replace the Power Transformer it was shot. I had to replace the 1 speaker Terminal Board 2 Broken Screws, had to Replace the VU meter’s Left Side wouldn’t work. 2 VU Meter Bulbs were out luckily I had an extra assembly on that, 2 circuit boards had it copper was a rusty mess. Inside Screws were rust. 2 Cabinet Screws were missing. I found the main trouble & it was a wire not soldered back in place, also the 2 power switch Screws were loose. I’m so deep into this Reciever & EBay won’t help me out. So I’ll just end up sending this unit in for Repair it’s beyond me now.

    Rust is never a good thing, all that humidity and you know the fine electronics are going to suffer.

    I've lost two Technics receivers that I was refurbishing that way, one (Technics SA-T670 receiver.) I'd shipped from the other end of the country and it shorted less than 20mins into my first listen :(

    What are the controls and fascia like? Worth keeping and hunting down a less pretty unit?
