Old Belles Two amp ?
Hi,
Few weeks ago I get this old amp now I like to restore it. After few unaswered emils to manufacturer I will like to ask few question on this forum.This is first time. 1.Maybe someone has the schematic ? 2.There D41D14 and D40D14(I not sure about this because is unmarked) driver transistor. Which newer one BD237/38 or 2N4920/23 I can use without any change on PCB ? Maybe some others can be use here ? 3.On output looks like I use MJ15003/4 it's a good choice ? I have not much even no expirence with SS staff I tube guy but I hope I can change the tranzistors and caps. Thanks for any help. Jozef
