nincs hiba csak technikai kérdés autóerősítővel kapcsolatban. pontosabban: TDA7850 4*50W 4Channel Stereo Car Audio Power Amplifi
A gyári fejegység tuningjáról letéve elkezdtem keresgélni erősítőket. Az elvárásaim csak annyi,hogy a 4x43w-nél nagyobb legyen, kicsi könnyel elrejthető legyen és a legfontosabb ne kelljen az aksiról tápot behúzni is a kocsit bekábelezni. erre gondolok: https://www.aliexpress.com/item/TDA7850-4-50W-4Channel-Stereo-Car-Audio-Power-Amplifier-Board-12V-XH-M150/32801116968.html?spm=2114.01010208.3.41.Bhq8i2&ws_ab_test=searchweb0_0,searchweb201602_3_10152_10065_10151_10068_436_10136_10137_10157_10060_10138_10155_10062_10156_10154_10056_10055_10054_10059_10099_10103_10102_10096_10147_10052_10053_10142_10107_10050_10051_10171_10084_10083_10119_10080_10082_10081_10110_10111_10112_10113_10114_10181_10183_10182_10185_10078_10079_10073_10070_10123_10120,searchweb201603_2,ppcSwitch_5&btsid=366164ea-4048-4cd7-b4f5-f02c249e90d2&algo_expid=9eddad31-2f11-4d34-856e-0108a3f79a36-5&algo_pvid=9eddad31-2f11-4d34-856e-0108a3f79a36 érdemes ilyenekkel próbálkozni?

Audio Amplifier BST XA-1000
Hi
I'm looking for a schematic diagram for this equipment:
Professional Power Amplifier XA-1000

The main fuse was blown and according the owner it blowns again after replacement.
He used a 40 amp fuse. The original fuse is not around anymore and there is nothing written outside on the label. So it's somewhat a lottery about the correct fuse rating.

Anyway, I would like to repair this equipment but without a diagram it would be a pain and nearly impossible.
Tryed to find a diagramwith Google search - negative. Also the manufacurer ist unknown this days.

Maybe a reader has more information aboutb this.

Thanks a lot
Redwood (74)
