Sequential Tube Monoblocks


Vintage McIntosh monoblock tube amps- MC 30 or MC 75.
Is it important to buy sequential units?

Hopefully, the OP will realize access to a competent tech/shop for necessary replacement of ageing  components/adjustments are the only requirement.

Once done, it will outlast its owner.

I'd like to have the period appropriate Mac amps/pre to go with my 67 MR 71 tuner.

What @tablejockey said is right. With something that old it's more important that each has been  modded or repaired if you will, similarly. 

otoh if they're 100% original, then they definitely need to be from the same batch of parts 

I wouldn’t think so, I would just make sure they are from the same or similar time period/model/upgrade etc. 

As long as they haven’t changed any parts, then I’d think you’ll be okay.
