After seeing what great work Andrea IW5CI is doing with classic U.S. gear in his SX-28 thread I thought it was important to acquire some classic looking Italian vintage gear to keep the planet in balance  A few months ago I acquired a Geloso G4/215 receiver and started looking for the matching G4/225 transmitter. I now have the setup and although working they will soon go on the bench for a full inspection and alignment. I do need to acquire some missing metal discs for the knobs and it would be nice to find a new dial cover for the transmitter (it has a crack on one side) but that is not likely to happen soon. The receiver is dual conversion with a single crystal style filter in the 467 Kc. second IF. The transmitter is a phasing type rated at 100 watts output SSB/CW and 25 watts AM from a pair of 6146 tubes. Both were made in 1965 and cover 80-10 meters. The transmitter VOX system is located in the separate power supply. It came with a Geloso microphone which will take a little getting used to, the microphone head lifts out of the stand when you pick it up instead of being permanently attached to the base. I think it will be easier to modify the microphone than my behavior |

I always thought the Geloso transmitter was like the Italian version of the Johnson Valiant.  |

That is a fascinating looking pair. Is Geloso pronounced with a hard or soft G? I am a little surprised the front panels are labeled in English. I wonder if there were export and domestic models.

I think the Geloso's look very stylish. Bright and uncluttered. The microphone is a real catch.
Mr. Geloso was quite a clever and interesting man. He worked here in the US for several years (I think with Mr. Hammarlund) before returning to Italy.

Rob,
I don't know which is the proper pronunciation.
The manuals that came with the gear are in both Italian and English (well a few sections are Italian only) but all of the photos of the gear show it is labeled in English.

I think the G is soft. Most hard G's with the e following have a second vowel, like gear, Geiger....

An interesting link for the Geloso Story (in English): http://www.qsl.net/i0jx/geloso.htmlGeloso means Jealous, the G is pronounced like the J. |

Cool stuff Rodger, you needed those! Think I've seen one of those at HossTraders some years back, not as pretty as your sets. Radio on OM. |

Rodger,
In your pix, you missed the money shot!! You should show the underside of the chassis!! For those who've never seen one, Geloso stuff from that era has the neatest wiring and cleanest chassis layouts I've ever seen!! True craftsmanship, and beauty to behold! ! ! ! ! ! ! ! ! !
One of the FEW things I dislike is the crapstal carbolator. It uses harmonics of 3500Kc instead of 100Kc only enabling you to cal the bottom of each band. (at least that is the way mine is)

Bruce, I am not sure need is the right word but they are a fun setup. Compared to the other radios I have been working with lately the Geloso gear is refreshingly lightweight. Slab, I will take a better look at them now that the HT-30 is off the bench. This receiver also has the 3.5 Mhz. calibrator crystal, it was such a great idea Hallicrafters used it in the SX-140 The cute little microphone is going to get some removable adhesive used at the joint between the head and the base before I accidentally send the base flying into something. |

Do they employ special wiring perhaps Teflon? |

Rodger,
Looks like a fun project. I have never seen one up and close but have always heard that they were well done.
At first physical glance, they have a shade of similarity to some of the Elmac transmitters. Functional equivalency seems similar to an HT-37.
When you have the pieces belly up, it would be good to see some underneath shots.
Have fun!
Joe, W3GMS

The G is pronounced like a J. Hence: Jeloso in english. (there is no J in the Italian alphebet) I have a Geloso receiver, (dont remember which model number) but it is similar in appearance to Rodgers. It is a good, solid performer and quite a pleasure to use. |

In the good old days when Geloso was in vogue I was not very attracted by their equipment (though I used their “Gruppi RF” and transformers) I was more attracted by the American radio equipment. Now I have to admit that they were not so bad, it’s a matter of nostalgia?

ZEQ used to run a Geloso 500 aka a JJ 813 rig I could never understand his humor? I told him once on the air, there is no such thing and he went off on me like you wouldn't believe!! |
