Thoughts On JVC AV-20F476

I have the opportunity to pick up a new JVC AV-20F476 locally, which someone won as a prize. I could only find one thread with a reference on this forum but the reviews on Amazon are favorable. Does anyone know anything about these JVC sets? The data sheet indicates it has vertical scan compression (16:9 mode) and velocity scan modulation on/off control. With these features, I suspect it will provide a better picture than any of the new small CRT sets. Thanks in advance.

Well I decided to go ahead and get the JVC. I haven't had much of a chance to play with it yet, so I don't know if I will need to make any adjustments or not. However, does anyone know how to get into the service menu of this set? Thanks.
