Tube Rolling with the Line Magnetic 518 IA

845 - Psvane

12AX7s - Mullard ECC83, long plate, goal post getter with code f91 on tube (about 1958), about $200 - 250 for a good matched pair on ebay from a good seller.

6L6/KT66: original (not reissue) Genalex, matched pairs $300 - 400 on ebay (a pair there now at $425 buy it now).

5AR4/GZ34: Mullard BVA or Phillips Mini-Watt, both metal base ($300 - 400).

You've bought an $8K integrated...treat it right. :0)

I'm about to take possession of a 518 and wondered about tube rolling as well. Would be ok to suggest some trusted/recommended ebay sellers?

Tried a pair of GE5751's for a couple of weeks then switched back to Nos Philips JAN 12AX7's. Phew what a difference 12AX7's made everything sound spectacular again. I guess the 5751's were too polite for me. Current compliment I am enjoying is the above 12AX7's, Mullard Nos Rectifier., stock 845's and Shuguang Black Beauty 6CA7Z's . Dynamic, involving, organic, all the good stuff.

tried the Psvane 845 II an the Psvane 845 WE Replica either one will send this amp to new level stuck with the 845 II ,just a matter of preference also replaced stock 12ax7 with the Psvane premium series TII and heard a improvement over the stock 12ax7,,

Just purchased the 518 and only have about 10 hours on it but very impressed with build and sound quality thus far. I went ahead and swapped in NOS Mullard 5AR4 and GE 12ax7s. May swap in NOS GE 6L6GCs after further listening.
