I have a 1960's Fender Electronic Echo Chamber that no longer puts out any sound. Does anyone know what type of fuse it requires?

Fuse is missing ?

3/4 amp slow blow. Size ; 1/4 " X 1 1/4 "

Thanks for the reply.
Is your language French? Ma femme est Française, but I won't try to communicate with you in French.
The fuse is good, the machine has power. I am now getting some sound from the playback head. I think the output jack needs cleaning. But the erase/record head isn't working. Maybe it needs a new one. I'm not a technician but the problem may also be inside the machine (wiring, contacts, caps, etc.) I will clean up what I can and see if that helps, but I may have to take it to a shop to see if it is worth repairing.
Your second link is the correct schematic:

This is what it looks like:

I hope I can fix this echo chamber.
Thanks again for replying,

Oui je parle français, je suis Québécois .
I fix amp and guitar for hobby, I'm a tech. I never work on these unit

Merci pour votre reponse. L'Anglais est ma langue maternelle.
Chantal m'a aide a ecrire ce mail. C'est une Franchouillarde de La Picardie.
Vive Le Quebec!
Thank you.

La Picardie c'est Yves Montant je crois et pour les plus vieux ?
J'ai été 10 fois en France et pas encore en Picardie.

Pour revenir à ta machine, je ne suis pas du tout connaissant dans ce type d'appareil. Je vai faire un recherche avec Google.

Picardy is Yves Montant I think and for the oldest?
I have been 10 times in France and not yet in Picardy.

To return to your machine, I am not at all knowledgeable in this type of device. I will do a search with Google

I'm not a technician but this is what a tech on another website told me:
"Looks like it is a solid state machine so you will need to replace ALL the electrolytic caps in it and Maybe one or two transistors. You probably have the old style clay magnet heads and those will probably be bad. If you get signal through you will have to check if the bias oscillator works then see if the heads are not open not to mention winding the spool so the tape feeds out the center. Make sure you can get the transport working right then check out the heads with a meter."
I don't understand most of that. It's French to me. I think I have to take it to a repair shop.

I don't understand what this means: "Picardy is Yves Montant I think and for the oldest?"

Thank you for taking the time to respond.

That is because you are too young
