Originally Posted by Crowbar Can the output stage be made a follower, so the tube does all the voltage gain, while still retaining DC coupling throughout? Obviously, the more replacement suggestions you post, the more will make it to the list before the list can no longer be dtaasheet.

HyperionNov 14, If anyone has any suggestions on how to accomplish this better, please let me know. I just arrived at this post, because I’ve been looking at replacing the original power transistors in my Marantz Er, it’s been a year since he posted.


I wonder if that’s as good as a follower then. Middle of Crook County. Log in or Sign up.

2SC (Hitachi) – Silicon Npn Epitaxial, NPN

Thanks for posting this Pete. I have to personally thank Avionic, EW, Ilimzn, Clinic and the other folks who pointed me in the right direction.

This above list is only meant to be a guideline and not a list of absolute substitutes. Link to dlucy flowchart for choosing a substitute transistor I datasheeg on it while searching for trannies replacements. The main thing you want to look out for is a high gate capactance which will turn the SE stage into a Low Pass filter if too high.

Transistor Substitutions

No, create an account now. The transistors, however, seem to have gone through more then one generation of replacements. Yes, my password is: Post 1 of Jun 27, at 5: Post 8 of And as we have just discussed in this thread Below is a very good decision path example provided by dlucy Thank you Dlucy and others that have shared your knowledge and added to the list and to this thread! Better on the PNP – just 1. TJacquesJan 18, I will try to make it available on a shared drive in the future.


The C moves the collector to the center pin. I obviously have this in Excel, but there are limitations on what can be uploaded. Anything one has the other should have. Make sure for any complimentary pairs that supplier gives you the same range for both, otherwise you might have problems. I’m sure he’s found them by now. See updated list below!
