Brimar 6C4/CV133/EC90 

One (1) piece!

These tubes come with black plates and big horse shoe getter. Different print styles available. Please see example pictures! Other than that all tubes are exactly the same inside and out.

We reserve the right to deliver either print style, since our stock is rather limited

These tubes are from the early 1950ies. 

These tubes came in bulk from Swiss army surplus. All tubes are tested and burned-in/pre-aged (hence the colors on the tubes). The burn-in was done to secure stabilized operation in highly sensitive measuring instruments. 

Some tubes may carry values written on them by the army personal or may have faded prints. This does of course not affect the proper operation.

All tubes are guaranteed to test as new!
