Remember that the more complicated something is, the more likely something will go wrong. As far as my experience, unless I was working on digital electronics (and then a logic analyzer is better) two channels on a scope is enough. Two channels allows you to compare the timing of two signals, you really don't do that very often on a TV. On some scopes the second channel is used for the X axis when displaying in the X-Y mode. For TV use a bandwidth in the 5 to 50 MHz is fine. |

In the states, Sanyo built most of the Sears products, with a sprinkling of Gold Stars, RCA's and Toshiba. Maybe the Canadian products are a little different. |

Oh snap, I mixed up the Japanese suppliers. Yes the set I spoke of is a Sanyo under the hood. However, I briefly had a worn-out 1978 Electrohome with a JVC-built chassis, the first model year they used them. It wasn't built nearly as well as the earlier models. It had vertical interval reference though, I kept the module as a curiosity.

Just updating this to say I was patient and found a Tektronix TAS220 (the last of the analog scopes) with the readout function for 85 GBP. With shipping it cost me around 120€ total, plus 10€ for some new probes on Amazon and I'm all set. It seems to work perfectly, though I'm gonna check calibration before using it for anything important.

My workhorse bench scope is a Tektronix 454. It's old, but does a nice job.
