Samos

Fri, 15 May 2020 09:22:46 +0000

A few days ago I picked up this Samos FuMB 4, it was used in western part of Denmark.

I need to restore some of the changes that was made of one of the previous owners.

Unfortunately, he made some holes in the front, that I have to close and paint.

The fuseholders is missing, but I have two spares, that I'll use for it.

The banana sockets missing, will be rebuilt with some used ones, I'll modify for correct looks.

I need to find another main switch, that fits the original hole in the front.

Some of the capacitors has been replaced, but I'll have to replace them by correct values.

Lo6L39 year?

Mon, 20 Sep 2021 18:19:34 +0000

I have a Lo6L39 serial no. 75972 that I have been restoring for many years. Now I need know the year it was produced, because Dejan will make the serial plate for me. I found a photo of a Lo6L39, with serial no. 76112 from 1940.

The tubes is all dated from 1943 and 1944, but since it was used by the danish navy, I guess they have been changed...

I didn't find any clues of a date inside.

I hope that you can help me, "guessing" the year it was produced, by looking at some photos:

The serial no. 75972 is stamped in the top:

The front:

Front inside:

Capacitors, normal type, not the ceramic type:

Some stamps in the top:

I really you can help me out :-)

it’s a vhf transceiver 37,5 to 46,2 mhz

This set is in grey marine color , we see 2 marks one round one where it’s written

kriegsmarine , and a small one a M. i have read in trenkle that the set is instable

and unsatisfactory for any use. I don’t know where it’s used , may be for harbour

ships like tugs , or fisher ship, i know they are used for recovering pilots shot down

at sea. I know it because there is in one notice an antenna for a one watt set, on board

fishing ships from 17V.P Flotille , it’s mentionned but without set name so it can be

also from LO 1 uk 35 also one watt., antenna strahler is 1,67 m and placed on top

of mast at 13 meter above main deck.

now the pictures of set
