EL34-Used zv1-tsu1038 NEW

Unknown

Used EL34, probably Philips... but markings are unreadable. Tested WEAK... sold as is.

 

We use following grades when testing our tubes:
+ GOOD:  Good or above electrical specs
= OK: OK or within electrical specs
- WEAK: Barely within electrical specs
We test our tubes with a tube tester on electrical specifications, internal leakage and electrical shorts.
Tubes that are way out of spec (with or without slight leakage) might be sold by us very cheaply as packs of 10 for fun or crazy experimenting! Tubes with internal shorts will not be sold by us, they go straight into the bin!
