Rádió skála hangolásjelző fogasléc mivel helyettesíthető?
Üdvözlet Mindenkinek!
A mellékelt képen egy Panasonic FW18 kétkazettás rádió-magnó törött rádióskála helyzetjelző fogasléce látható. Eltört, mert öreg és rideg,  a műanyag nem hagyja magát megragasztani. Megoldás lenne, ha csak a fogasléc részét pótolnám, de ilyen kis méretű / 3x1,5 mm / fogaslécet égen-földön nem találok. Abban kérném a segítségetek, hogy hol lehet ilyen kisméretű fogaslécet beszerezni, vagy milyen más megoldással tudnám a problémát megoldani.

Megoldás:
TonyStark ötlete alapján megfelelő méretű kábelkötözőböl a két szél levágásával csináltam egy, az eredetivel megegyező méretű fogaslécet, és a skálajelzőre ragasztottam.
Kitűnően működik. Köszönöm a segítségeteket!

Üdv.

helyettesíthető-e vele?
Van egy Marantz Pm-64 típusú erősítőm. KIment belőle az STK3102IIA meghajtó stk fél oldala. Ki kellene cserélnem. Ilyen stk.t már nem találok, de van helyette STK3102III. Helyettesíthető vele? Előre is köszönöm.
Aiwa RX-30 -ban a 3SK73 helyettesíthető-e BF964-el? És hangolási hiba.
Sziasztok! Egy Aiwa RX-30-at javítok, tuner-hibás. A 3sk73-ra terelődött a gyanú. Az volna a kérdésem, mivel semmit nem találtam róla, hogy helyettesíthető-e pl. BF964, vagy BF966-al? Persze, megfelelő lábelrendezés után. Köszönettel Attila
Trio-Kenwood: KR-3010 [Radio] S.N.962845 / Does not work, the final floor and prefinal floor defect with many burned component/

I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part

If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
