Скачать или смотреть Denon DR-F8 - Trying New Grease On An Aggravating Cassette Deck

I decided my life needed a lot more drama this week, so we're working to bring my Denon DR-F8 back to working order today. This machine is one of only two quartz locked direct drive auto calibrating models ever made from Denon, and I've been curious about it for a long time.

We're also going to check out some new grease today to see if I can raise my game just a little more before I start working on these for other people.

Idler: 11 x 15 x 1.8mm (from an Aliexpress "Conpile" random idler kit)
Counter belt: 228mm IC x 0.7mm square
Pinch roller: 13 x 8 x 2.5mm

Monitor & MPX switches: ALPS 2x3 pin latching type, panel mount. 4mm pin spacing, 6mm row spacing, 20mm bracket mounting hole spacing. PBS-22H18A appears to fit, but measure yours first to be safe.
