Phil’s Analog Basement

I purchased 100 new old stock in box General Electric 6GH8A vacuum tubes. Made in their Owensboro KY factory. This should be a lifetime of tubes for any work I do on Dynaco and some other gear that uses 7199, 6BL8, 6U8, 6AN8, etc (with the appropriate adapters of course)

I am tempted to buy one of these new FiiO EL34 integrated amps, just to test it on my audio analyzers and provide a technical review, since it seems nobody has done it yet.

I don't need it afterwards, would anyone in the Rochester, NY area be interested in buying it after the testing is complete? It seems like an interesting amplifier as far as inexpensive new production tube gear is concerned.

Finally got around to trying out this Eico ST 70 that I bought back in march. It was partially restored by the prior owner but still needs some work. On the plus side it has some nice well matched tubes in it - including amperex 1960s bugle boy 12ax7a’s
