[Jukebox-list] Scope for Wurlitzer Amplifiers?

Hello,

Is this a suitable scope to troubleshoot Wurlitzer amplifiers? Would a signal injector be required as well?

I have only done a few basic repairs and servicing, so am still a novice.

If it can be helpful, would appreciate early response; there is time constraint to ask a friend to assist with the purchase.

Many thanks 🙏
