Rebonjour à tous
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.
