Kakve veze ima boja? No, poznavajući Dadod-a, ili su plave ili zelene. Tako da ... boja je najmanje bitna.

Zelene su, nekako me najmanje zamara lamljenje na zelenim, a mozda neki vole u lemiti u crnam mraku.

Odlično, zelene. Meni se sviđa.

Meni isto.

[Zmajz]

Vidim od tih 20 komada ima mjesta i za jednu za mene, stoga:

[Bepone]

koliko je sad 18? ako je raspolozivo 19.. onda neka bude i meni jedna?

[dadod]

Stigle plocice, iznenadjen brzinom i kvalitetnom dostavom.

to je ukupno 20.

Danas cu pripremiti potrebnu dokumentaciju (imam ju od prije ali cu jos provjeriti) i vidjeti cijenu, bit ce povoljno a pogotovo za one koji dodju do mene i tu ih pokupe.

Otpornik R32 od 2R2 se moze i kratko spojiti ili povecati, sto ovisi o koristenim slusalicama. Probati pa odluciti. Neke slusalice vole visoki damping (vrlo mali unutarnji otpor pojacala, a neke bolje sviraju kod manjeg dampinga.

2SK170BL problematično za nabaviti!
Da li ima adekvatna zamjena?

Simulirao sam s J202, igleda da on moze i ima kod Mausera. Drugaciji raspored nozica nego 2SK170.
Naravno LSK170B i LSK170A nadje se na velikom forumu u DIYAUDIO STORE.
Kod TME ima MMBFJ202 doduse SMD i moglo bi se prilagoditi. https://www.tme.eu/hr/katalog/tranzisto ... ld=1000011" target="_blank" target="_blank" target="_blank

Mozda se jos nadju na webu i 2SK170GR isto dobro.
