I bought J162 and K1058 pairs from Hong Kong seller on ebay.($17 for 4) They blew up on 30v rail. They supposed by Renesas product, but it dose not bear any marking of such. I was replacing shorted Hitachi parts. The channel is working with transplanted Hitachi pair from other channel. I also bought 15000uf 100v filter caps on ebay from FL seller, it passes too much ripple on 80v rail resulting too much ripple humm. This cap supposed to be new and price $16/pc. I am using my salvaged 10000uf caps for now with better ripple noise control.

I guess I learned lesson on the hard way. But it was too good a price to pass on them.
 
yes, heaps of fakes, but also some good paerts from good sellers, which makes it very difficult. but after enough bad experiences with 'NOS' parts I decided to give it a miss altogether despite the likelihood of missing out on some good deals
