Mullard/Hammond GZ34/5AR4, I purchased this as NOS (early 1960s) from Vintage Tube Services 4 or 5 years ago, I put about 1500 hours on it, no box. $40.
Ken-Rad 5Y3G VT-197-A, (coke bottle) I purchased this as NOS 3 years ago. I put about 100 hours on it, no box. $12.
Sylvania 5Y3WGTA, I purchased this about 2 years ago. I put less than 100 hours on it, box is rough. $12.
Sovtek 5Y3GT current issue, I purchased this new from AES 6 or 7 years ago, I put about 300-400 hours on it. $10.
