Reloop 1400 erősítő
Kedves kollégák! Szert tettem egy fent nevezett kínai csodára...nagyon pofás kis erősítő, egyszerű kapcsolás. Szemre olyan 5-600W-os toroid, kicsi hűtőborda, két venti. Problémám az, hogy a ventik nem kapcsolnak be. Van a bordákon két hőkapcsoló. az egyik egy NC-állású, ez a védelem reléjét oldja, ha túlmelegedne (szerintem olyan 60-70C-fokos lehet...). A másik egy NO, ez akkor kapcsolná be a ventiket, ha már érezhetően melegszik a borda... Na ez az ami nem működik. Kérdésem az, hogy honnan lehet ezeket beszerezni??? mi a nevük??? kb.12-14mm átmérőjű 10mm magas henger, hátán két faston-saru... egy tojás alakú gyűrű segítségével, két csavarral rögzíthetjük. (olyan, mint pl. a kávéfőzők hőkapcsolója...) cél, hogy 30-35C -on kapcsoljon be,12V-on,max 1A-t. Előre is köszi a segítséget!!! stonhy
ION Archive LP Turntable

This is a compact design to I guess transfer the vinyl into MP3 format.
Complaint was when the arm was moved the tt dont spin, confirmed that as
theres a leaf switch to sense arm movement,
and its fed to a main pcb with all the IC's that I guess handle all the
stuff. The switch is ok, and I remember seeing 14V or so on the motor pins
frm the PCB, so I figured perhaps theres anough current to spin the motor and
focused on testing the motor.

Manufacturer does not supply the mainboard that feeds the motor but
the motor can be taken apart and after I opened it and
disconnected the small pcb fron the motor terminals and apply power
directly, it spins w 12v. theres a small electrolytic cap on the pcb 25V / 22uF and an
AN6652 4 pin T0-220 type case IC that I guess is some kind of speed control
circuitry.

The drive Motor is an EG-530-SD-3F, main board is stamped K-13007.
Gonna check the cap, but after searching this IC and its
applications with the motor, I see its popular and some drawings show how its used to regulate the 78,33
and 45 rpm speeds.

This drawing looks pretty much what I see in there:

I have replaced the IC and the cap, but the motor still does not turn. The main pcb

is proprietary and cant be purchased, and I think it is giving the op-amp IC a reference signal.

Is there a way to bypass that signal or fool the IC to believing its on to test it out?
