Just like there's probably very little in the way of manufacturing left in the world for this type of incandescent lightbulb as similarly found in power tube manufacturing - makes it possible to produce junk and still sell as many as can be made.
This type of stereo gear is very much in demand now amongst the hipsters and similar generational youth. The reto-chic is very desirable it seems. For me, this is the same as it ever was. (Ugh, I dislike regurgitating that phrase because it's been co-opted by some ersatz cool kids ad nausea. And David Byrne is as cool as they get so the perversion must be bittersweet.)

Hahaha ain't that the truth. I was collecting and repairing that stuff before they were ever a gleam in anyone's eye lol
So if it is a DC supply maybe it's a poor DC voltage, like as in half wave rectifier poor. And then it needs to ramp up during power up. I used to have an all tube recording channel, and an old Cuban man that worked in the business since Sinatra told me that the only way to preserve the life of the tubes was to have a clean supply and to slowly ramp up the filament voltage first when turning on the console.
That said it's probably more trouble than it's worth, though I'm sure some hipster electronics genius will come up with a small PCB to add into the DC power buss to accomplish this ;-)
