Title: Cap and resistor upgrades
Post by: MikkelR on September 14, 2018, 04:40:21 PM

Hi all,

New here and new to Bottlehead. I bought a used Eros and are looking to upgrade the output coupling caps and the resistors referenced here:

There's also a 0.1uf cap in the shunt regulator circuit that's potentially worth upgrading.  A 400V cap is OK here.

The 75K 1/2W and and 47K 2W resistors are also very much in the signal path, those could be upgraded, but be sure to use 1% parts or buy enough to match.

I got matched parts in my drawer and can solder, what I don't have is the manual. I want to make sure I swap the right resistors.I have a decent idea which they are but would appreciate a pointer, especially for the 75K 1/2W's.

Best

You can use a meter to measure the value of most of the resistors in the Eros.

Thanks Paul, Absolutely will! Was merely looking for a pointer as to where the 75K 1/2W resistor is located before going over all of them without a diagram  ;D

Under the front C4S boards.
