Hello all.
I am the nube. My area of expertise? Timber.....
In order to learn , I have decided to open the chassis of my tecnico fortress, find a suitable schematic, and start deciphering.
However, my schematic, sourced from RMorg , states valves completely different to what is actually in it. But the valves in it DO check out with the information page from which the schematic came. Is this a normal kind of thing? I did research each existing valve, and I feel they fit the bill- ie actual 5y3gt seems to match the schematics 5z4g, in as much as they are a rectifier. ( 6av6 where there should be a 6b6g,detection, and 6be6 for a ek2g converter. And the 5th is 6ba6 for a 6u7g, I.F. I could also be completely wrong.😬
Anyway, I would like this radio to be a first foray into recapping. I’ve read a few learners guides to recapping. I have documented all the existing paper and electrolytic caps, except for two paper caps who have no paper left ( melted, burnt, stuffed). I am trying to work out which these two are, on the schematic 🧐 .is it safe to just replace with caps with high values? The schematic seems to list capacitance values, but not voltages. I have been consulting conversion tables to find what caps to buy. It’s a bit daunting, but I will work it out! Any constructive pointers welcome!
Regards, murray

5Y3GT and 5Z4G are both rectifiers.

6AV6 and 6B6G are both duo-diode triodes

6BE6 and EK2G are both frequency changers

6BA6 and 6U7G are both IF amplifiers.

The unknown paper caps could be replaced with 0.01 or 0.05 to start with and see how you go, but see if you can find out from the schematic first.

Some radios went through evolutionary changes, for example the Kriesler 11-7 went through 27 different valve line-ups, I think it was.

If you're having trouble getting the correct caps there are some members that keep stocks of them for reasonable prices.

Hi Muzzery I have the appropriate caps if you need them just email me. My email is there to see. I also have kits if you wish

Hi Murray

Go to https://www.kevinchant.com/uploads/7/1/0/8/7108231/1050_1050m_1051.pdf

There is a much clearer circuit diagram there. for the 1050 series. Much easier to read than the one on radiomuseum site.

By process of elimination you could have a good stab at what the values should be... OR. up load a photograph ..and I'm sure someone would be able to identify where they are on the circuit diagram for you.

Ok, thanks for the replies. I have ordered a capacitor kit off eBay, and had a chat on the phone with the vendor. Along with advice on this forum, I’m feeling more confident, and always learning! I also was given a couple of old sets- a plastic case Kriesler table set, and a record player/ three band combo by GEC. So I will have plenty to keep me busy! The GEC has a brilliant service manual excerpt which I downloaded from rm.org. I learned a lot from this before I’ve even lit the soldering iron! So I look forward to starting recapping.
At what point of this hobby would one consider aquireing a variac?

A dim bulb tester is more useful and kinder to the equipment under test. And cheaper. And safer. And you can let stuff run unattended knowing it will be safe.

I have a variac. I NEVER use it.....
