6GH8A Matched pair ECF82: EI PHILIPS

Type: ECF82 6GH8A

Auction is for one platinum matched pair (2 tubes) of rare 6GH8A EI Yugoslavia (ECF82) made back in 80s for export. They come in original EI Yellow Blue boxes.

They are made on original Philips Heerlen tooling and they have passed strict quality control for export under Philips, Siemens, Telefunken and Valvo brands.

They can be used in modified Dynaco ST-70 PC-3 board which accepts 6GH8A instead of scarce 7199. They also can be used in original Dynaco ST70 driver board using special noval adapters.

I have few 100 pcs packagings of these tubes and all pairs I have are carefully tested and matched by plate current on my Metrix U61-B tester. Due to big number of tested tubes, they are matched within 5% or less!!!

Good quality 😍
Color: Ice Green, Size: Large
I really like this shirt! The knit material feels soft, breathable, and perfect for warm weather. The design looks stylish and modern, exactly like the pictures. It fits true to size and sits really nice on the body—comfortable but still fitted enough to look clean. Great for summer outings, brunch, or beach vibes. Definitely worth the purchase
