I don't know what model that circuit I posted was from as I found it 'as is' on t'interweb.
I quite agree about things not meeting modern standards but can't say it bothers me, though it would if I were dealing with such things professionally.
I have heard that old equipment has to comply with the regs in force at the time it was made. If it is modified the new ones apply. Where 'repair' becomes 'modify' I've no idea; if you re-cap a radio you're modifying it from wax to polyester capacitors of slightly different ratings to those specified by the manufacturer in the past.
