Default Selena B215 quiet FM fixed

Got a Selena power lead off ebay for 26 delivered. It had a B210 with it, gave it a good clean but it was already cleanish and it works great, a couple of knobs are broken but still in place and fairly secure. This inspired me to have another look at my B215 which was quiet on FM, compared to the B210 it is noticably quieter all around. Using some info on this thread: https://www.vintage-radio.net/forum/...=169545&page=4 I replaced those little pF caps and measured the old ones C5 should be 51pF measured 57, C19 should be 24pF measured 83, C27 should be 24pF measured "no capacitance", C32 should be 24pF measured 95 and C53 should be 51pF measured 38... Replaced nominal 24pF with 22 and 51pF with 47, and it works. Probably needs realigning now, also might be worth replacing the axial electrolytics on the IF board to address the general quietness but it's great to have a successful fix, thanks to hobbyists.

Peculiar differences between B210 switch operation on battery vs mains. Momentary light button switches lights on for battery, off for mains. On mains the red switch button switches the radio off but leaves the lights on when pressed in... the radio is switched on by pressing the sine wave button in and leaving the red button out.

I like the Selenas, and the Parker Knoll set is a bit of a classic too

I imagine that's like taking coals to Newcastle, I enjoyed reading this Cuban angle: https://www.radios-tv.co.uk/communit...soviet-radios/

That (Ercol!) kitchen furniture is about the same age as the radios on it, plenty of life left in that too.
