Shakedown, the only time I've heard or seen a hole having to be cut is for a different RECTIFER tube than the 5AR4/GZ34. The small 9 pin tubes have no problem with clearance of the lid. I tried at least 9 or 10 different brand/styles of tubes and had no problem with any of them.
The Amperex Holland 7119's show up here on AudioGon once in awhile. You might check with the usual suspects, (Jim McShane, AZ Tubes, e-Bay). I did find several pair, but it took me a few months. You might need to be patient.
