PERSONAL TUBE COLLECTION AT SALE PRICES

It's that time of year to make room for new things, ideas, and thoughts in our lives. I have time to evaluate my personal tube collection accumulated over the last few years. Most of the items are hard to find in pairs, let alone in quads, matched, and tested. Some are truly rare, and all were acquired solely for sound quality, regardless of price. Now, it's time to let go of almost all of it for many reasons. Maybe I no longer have a place to use it; some were bought for testing equipment on review, or I have already settled on one alternative, and I don't think I will need another spare.

All of them are tested, measured, and bought from serious vendors and online stores. I tested it all personally, and it works as advertised. Even the NOS are quite NEW old stock and not used staff. I tried to provide as many details as I could, and I can follow up with more pictures for some serious buyers.

Prices are negotiable only when purchasing multiple items. Thank you.
