I just got my 1990 JVC TD-V531 3-head dual capstan cassette deck back. Unlike the TD-V661, this does not have a built-in tone generator. So how do you calibrate bias? In this video, I give you a quick demonstration.



I'm not sponsored nor do I have a Patreon, but if you want to support me and you're looking for a new US mobile carrier (or if you're looking to port your old number to a new carrier), you can use my referal code here when you sign up for Visible.

Code is: 3PGG8VR

Or use this link:
visible.com/get/?3PGG8VR

I'm an actual customer of Visible, and when you use my code, we both get $20 off for the month.

A bit more info on Visible:
Basic plan is $25/mo and gets you unlimited call, text, data, and 10 Mbps hotspot on the Verizon 5G Nationwide network (up to 400 Mbps depending on coverage)

Plus plan is $45/mo and adds Verizon's 5GUW (can go much faster than 400 Mbps depending on coverage) as well as mmWave service.

Check Visible site for updated plans as they may have changed since I put this up.

So this is how you can help me out! Thanks!
