I personnaly own a Grommes 500 M Receiver With 7868 Tubes, can't find any information on the web about it, not even from Grommes...

Do you have some pictures of your 500 C Grommes receiver? Maybe we can help each other!

My mail is felixlaurencelle@hotmail.com

Have a good day!

I have the schematics for 500M

I have just joined this forum so that the reply is quite late. Let me know if you are interested and I will scan and send here.

Please do scan the schematic and post it here. I never heard of a Grommes 500C or 500M receiver before.

Hi FulvioS! I'm still alive and I just saw your message, i would be interested to get those schematics if you still have them!

Thank you!

You know Grommes is still in business? Ask them! (They may not want to bother for 50+ year old gear, but worth a try.)
