The 6688 (European: E180F) (Russian: 6Ж9П) (P/N 154-0215-00) is a miniature high-slope VHF/UHF pentode vacuum tube with a B9A (Noval) miniature 9-pin base, primarily intended "for use in wideband amplifiers in telephone carrier systems, radar equipment and measuring equipment".
It is used in:
- the staircase generator circuit of the 3T77 and 3T77A
- the P80 cathode-follower probe
- TR-4602, Hungarian 551 clone
- the 526
- the 4S2A
