My LD II is in need of tubes (1K2 and 4P1S ) and I am having trouble finding a reliable, domestic source. S/H from China costs as much as the tubes themselves. Can you help me?
Thanks!

1T4 seems to be a sanctioned Western substitute for 1K2 in this amp. The European nomenclature is DF91.

Russian 4П1Л aka 4P1L can replace the Chinese 4P1S. Ukrainian and other sellers on eBay have plenty of 4P1Ls on offer.
