Yuriy is excellent supplier of tubes

Do not be concerned if Yuriy does not use Paypal. You will have excellent service from him, and your money is OK. I have bought GU74b power tubes from him and they have always arrived fast, with tracking number provided. If there are any problems with the tubes he has replaced them fast with no issues about it. HIGHLY RECOMMENDED.

Purchased pair of MELZ NOS 1578/6N8S/6SN7GT/ECC32 Holes T-Plates tubes Metal Base from Yuri. Most difficult part was paying him. I too was skeptical as he does not use Paypal and wire transfer fee was too high for small amount transaction. Took a plunge and decided to use Western Union. Yuri followed up with tracking info and updates. Received tubes yesterday and oh my. One of the best packing job I have seen. Just wanted to share my experience and give him 2 thumbs up.🙂 Now I hope these tubes work out in my SLI-80.
