Sony TC-K35 bad muffled recordings

[salvo79]

Ciao a tutti sul forum e grazie in anticipo. Chiedo aiuto riguardo al mio Sony TC-K35, a cui ho fatto un po' di manutenzione dato che era fermo da almeno 15 anni. Ho sostituito entrambe le cinghie e pulito l'intero percorso del nastro, inclusi rullo, capstan e testine. Il giradischi suona molto bene, ma purtroppo è pessimo in registrazione. Registra con una qualità pessima a volumi bassi e ovattati e senza alti. A prima vista, la testina non mostra segni evidenti del tempo, anzi, è piuttosto lucida. Non ho regolato nessun trimmer perché non ho capito qual è quello giusto. Ho provato con diverse cassette ma senza successo, quindi credo che il problema sia del giradischi. Allego il manuale di servizio. Ogni consiglio è ben accetto. Grazie a tutti e buona domenica.

Hello everyone on the forum, and thanks in advance. I'm looking for help with my Sony TC-K35, which I've done some maintenance on since it hadn't been used for at least 15 years. I replaced both belts and cleaned the entire tape path, including the roller, capstan, and cartridges. The turntable sounds great, but unfortunately, it records terribly. It records with terrible quality at low, muffled volumes and no treble. At first glance, the cartridge shows no obvious signs of aging; in fact, it's quite shiny. I haven't adjusted any trimmers because I haven't figured out which one is correct. I've tried with several cassettes, but to no avail, so I think the problem lies with the turntable. I've attached the service manual. Any advice is welcome. Thanks everyone, and have a great Sunday.
