RadioSvit,
Has a continuity test been done on the catacomb and did it pass?
Are you missing the cover for the tubes?
Has the sound reproducer been tested for music reproduction?
Often the cover jams on the reproducer, the cover is part of the diaphragm spacing adjustment, the internal gaskets harden, making the reproducer sound awful...
If you are in the Ukraine, do NOT let your eBay seller of tubes ship tubes by eBay Global Shipping. To eBays shipping partner contractor all tubes contain mercury because they are silver and are confiscated. Money is returned but no tubes...
Hint, avoid Song-Bird brand, very fragile both the glass envelope and the filament. The Silvertone brand with the box plate and the hair-pin filament are the most rugged.
The catacomb is built without internal shielding, it will not work properly with substitute tubes...

Site states foreign orders are welcome...
You will find this article useful: http://www.nostalgiaair.org/References/A...lash08.htm
One of the charts has a filament voltage error, too low...
