Capacitor and tube upgrade for Von Gaylord Lad L-2

I recently purchased a new Von Gaylord Lad L-2 preamp and the owner told me that this preamp can be improved with upgraded NOS tubes and capacitors. Has anyone with a stock Lad L-2 had this upgrade done? Can you tell me what was done( what brand tubes and caps) and what you thought of the sound improvement after the upgrades?

I looked up the Lad2 pre-amp. It uses two 6SN7 tubes so you are in luck as far as tube upgrades go because you can still buy beautiful examples of NOS or just OS (Old Stock = used) Tubes. The only way to know which tube you will ultimately like, is to try some. IN general the more expensive an NOS tubes is... the greater is the demand for good reasons. To save you time but not $ try Sylvania "W"s or GTs for an all around great sounding and stage throwing 6SN7. If you like anything specifically such as bass (iness) let me know and I can give you some suggestions.
I don't know about the capacitors.

I would still try the bottom getter Sylvania GT 1940s thru early 50s, Often referred to as the Bad Boy type. True Bad Boys are three rivet plate bottom getter GTs made from late 51 to early 53. Those tubes are special but not a requisite for the flat response you want . The Military version of the Sylvania bottom gettered GT is the VT 231.
