~~The 3T77 uses [[2N976]] transistors and [[1N3129]] [[tunnel diodes]].~~

==Internals==

~~It uses a [[6688]] tube in the staircase generator circuit.~~

==Difference of 3T77 and 3T77A==

While still tube-based, the 3T77 uses [[2N976]] transistors and [[1N3129]] [[tunnel diodes]].

It uses a [[6688]] tube in the staircase generator circuit, and an RCA [[7586]] nuvistor as a ramp-current generator.

The 3T77 mixes "classic" chassis/[[ceramic strip]] construction with the trigger circuit built on a PCB.

===Difference of 3T77 and 3T77A===

Time-Postiton instead Delay-Knob, with more range of delaying by slow sweep rate.

Recovery-Time-Knob can be pulling for HF-sync.
