And the 7104's ~1V/cm jug is good to 3GHz as well, a fact exploited in specially modded versions of the 7104 sold by at least one company (B&H Engineering) back in the day. The cost was given in dBdollars to help soften the sticker shock.

Bon courage, sure you will fix it,

The 7A29 have very special elastomeric switches AC/DC and attenuator that are prone to intermittents.

Use special precautions in cleaning as per manual.



PS This fine instrument is a real classic, the fastest analog CRT scope ever, originally for US AEC nuclear weapons testing. We are very lucky to have such a great design revitalized and in our labs. Vive la Tektronix !
The Soviets had 3GHz direct display scopes.
