Hi!

I can confirm that the TMB272 has a double–wound isolated mains transformer so it's completely safe to work on!

Some of the earlier small–screen KBs have a heater transformer so although live chassis, they're parallel heaters so no horrible droppers to crumble away or go o/c, if you find one of these they're well worth a punt!
