Hi Roger,

At least you spotted that - a lot of people would just see the mains transformer and assume it were an isolating tx.

In essence, treat this like you would a DAC90, as after all, it has neutral (hopefully!) connected straight to chassis.

e.g. make sure the knobs are present and correct, and securely attached; that there are no chassis screws accesible to be touched; that the back cover is undamaged and secure; and that no external LS or aerial etc. are connected. I would also ensure it's fed from an RCD-protected supply, and I'd also keep it out of the kitchen.

Good luck with it,
Nick.

P.S. If you want a nice-sounding, really well made, Bakelite set with VHF and a proper isolating transformer, look out for a Cossor 524. Fragile knobs aside, they're wonderful IMHO.

Sorry, crossed with the others, apologies for duplication. And interesting to hear about the advantages of this type of design, Tim, thanks!
