So here we go !
The Dynaco 30XL as they were sold to me seem very much being A 35 after all ?
The chamber interestingly is parted in a dampened 30x27x20 part and a similar sized empty upper cabinet housing nothing but the tweeter .
The port to the upper is covered with a cloth.
The gunk old stone wool had been reused when rewired - not sure if the caps are still original ...
I wonder if any one has altered these in specs?
Most of all I require the Inductance of the coil please!
Any information would be greatly accepted - 😁
