Thanks for the feed back. It REALLY helps me keep moving forward and builds my artifical confidence

I just have two more sets of capacitors that I need some advise on.

#1
These small, brown, 0,04uf 150v look like molded caps

Should I change these out?
Any idea what they are for?

I noticed on this particular capacitor set that they do not appear to match the schematic. I only see two on the schematic

Any advise on these caps would be of great help to me

#2
Capacitors C846, C847. Wierd little tiny wire tube ones and an unmatching golden one

The schematic says 12, so is that 12pf?

The picture shows the two different caps one is clearly marked C847 and the other is the gold one, Should I change to match these? What are they for?

Again please advise


These pictures show lots of oldcaps that have been changed already, so don't flame me for the electrolytics visible.thanks

OK I replaced the brown molded .04uf 150v with .047 250v orange dip caps

I did not change the 12pf caps. I have some 22pf caps if I need to change those

Man am I SCARED to power this up. I have been checking and rechecking my work for 3 days now.

Time to power it up TONIGHT

C846 and C847 are denoted with an extra "dot" on the schematic which probably denotes the side that the outer wrapping of the capacitor is connected to. This is done to minimize noise pickup. I'm guessing that these don't need to be touched. As long as the correct value of fuse is installed (never assume!) you should be okay to power it up.

Maybe it's a little too late, but i once saved this website to my favourites: UK Vintage Radio Repair and Restoration - Capacitors
It could come in handy, if You've been bitten by the "upgrade bug"

Edit. One more, use Google translate: http://www.py2bbs.qsl.br/capacitores.php

And this one: http://my.execpc.com/~endlr/index.html

I powered it up and it works! Sounds great. Nice and clear

So a newbie CAN change caps and resistors and by being careful saving money by doing it yourself

Thanks for everyone who assisted and advised me in this, my first re-cap of a tube amp

Now I am going to recap EVERYTHING

I am so happy

Default Full picture of the Blaupunkt

This is a picture from when I first unloaded the unit from my truck and was powering up the air compressor to blow the HUGH amount of dust from the chassis.

Wow.

Do a great job on it- let your work be an upgrade to the original craftmanship- This thing is a CLASSIC an will live for a very long time with a bit of care.

Very good idea, replacing ALL the 'lytics!

You've got a real gem there- ENJOY!
