I’ve an L-07D, PS-X9, TX-1000, and a couple MK3 in front of it.

Nah, won't cause damage.  A lot of techs will reflow and add a bit of solder and it's usually not an issue, or it lasts long enough it doesn't matter.  This is one unit where every factor is against you, so the chance of joint failures is high.  I...

Vintage DD turntables. Are we living dangerously?
Hi Halcro, I don't know the the patent applies due to the date as pointed out.  Appears to be interesting reading that I hope to get to at some point.
