The level of multipath is indicated by the brightening of some of the segments, starting from the left, so the goal is to orient the antenna such that there are no bright segments. On the T-7, which has a 20-segment light bar, the light dims and continues to indicate the signal strength in the multipath position. I think what happens is that the button, when pressed, changes the response time of the meter by switching to a different low-pass filter.

One is supposed to orient the antenna to achieve a steady reading. When the 'multipath' button is engaged, the wavering of the needle is a measure of the multipath. On the T-1 and T-2, the meter indicates signal strength in the normal position.

"The 'signal quality' meters on Yamaha tuners have always been a small mystery to me, but checking the manuals cleared it up. The last three tuners made after that were all basic models intended to pair with Yamaha's home theater amps: TX-470 in 1993, TX-480 in 1995 and TX-492 in 1998. "Concurrent with the TX-930 were the TX-330 and TX-530 in 1989, updated to TX-340 and TX-540 in 1990. The TX-1000/2000 were clearly their last great tuners. My guess is that the TX-1000 and TX-2000 were really new products and the TX-930 and TX-950 were their cheaper descendants, as Yamaha started to get out of making tuners and focused on DSP and A/V receivers ever since. The TX-1000 and TX-2000 came out a year later, in 1988, at higher prices, so the TX-900 didn't get much attention. I was astonished at how much the layout of the TX-900 looks like the T-85: 10 presets on the left, a large and busy display in the middle, small buttons below it, tuning/fine tuning buttons on the right. It's also interesting to note that these later models have the same basic layout as the TX-900, but they used a large tuning knob instead of the tuning bars. The later TX-1000/930/950 replaced the TX-900 as Yamaha's flagship model.

From then on, the two and three-digit series merged into the TX series in 1987 with the TX-400/500/900. In the 圆0 series, the lower-end models were analog but the T-760, T-960 and T-1060 (which looks exactly the same as the T-70 except it's silver and the T-70 is black) were digital. (The T-60 from 1991 was a low-end model.) These were all priced in the $400-500 range. The T-1 and T-2 caught my attention then because they were very slim and other tuners in that era were 'shoe boxes.' The T-7 came out in 1980, probably as a replacement for the T-1. They were concurrent with the CT series that were styled to match the integrated amps. Thanks to our late contributor PZ for this history of Yamaha tuners (additions and corrections, like Ryan's below, are welcome): "The T-1 and T-2 debuted in 1978 when Yamaha started to sell separate pre and power amps. Please post in our FMtuners group if you have any information about any of them. There are many Yamaha tuners in our On-Deck Circle that we'd like to consider listing here if our readers will provide some basic information on them (types of controls and features, and any personal anecdotes or comparisons to other tuners). We have posted updated eBay sale price data on this page through August, 2011 data for "as is" or damaged tuners, or otherwise unrepresentative auctions, may be excluded. In parentheses after the model number are the year of introduction and most recent list price, and/or the original list price if indicated by "orig." Special thanks to David Rich of The Audio Critic for copies of historical material from his reference library. Tuners are listed in alphabetical and numerical sequence by model number.
