Excellent woodworking!

I'm surprised that RCA red base 5692s have made it as far as Hanoi. Great tube.

There were many USA tubes in Viet Nam from the Viet Nam-War. We have many kinds of them. This tubes used in my Pre-Amp have bought from eBay. Now I have got around 100 tubes of 5692 red base in many lables as RCA, TUNG-SOL, GE, RAYTHEON, WESTINGHOUSE... Most of them are NOS.

This Pre-Amp is very good. I will post it's schematic late.

I have been to Hanoi couple time. I just love to collect the wood carving over there.

The woodwork is so beautiful and I love it very much.

Excellent work. By the way, you must spent some money acquiring over 100 pcs of 5692 tubes.
