Yup, it does have the blue meters. According to the silver pioneer
website,
ths was their flagship deck in 79 and 80 ... a 3 head model with tape
calibration facilities. build quality is strikingly rugged ... I've
seen receivers with smaller transformers than the one in this sucker!

Still have my fingers crossed that it will be a relatively simple fix
to get it up and running again. (hopefully just a few common
components...)
