Larsholt Tuner 7255 datasheet wireing diagram

Hello everybody !
I`ve got a tuner 7255 but no informations about himself. I`m looking for wireing diagram, technical datas or other stuff to get him running.
Also it`s interesting for me to get informations about newer tuner
from larsholt especially dual-mosfet.
Thanks.

Hi, is the tuner a complete printed circuit board with pins along one side and a box mounted on it containing the RF circuitry? If so, I might be able to help.
A photo would be useful but not essential

Hi,

sounds good. My modul is the same as descripted from John. Also I tryed to get a LH1037, but larsholt gave no feedback after couple mails. So I would be glad to get a offer for this - or moduls they are produced during the last 8 year, if possible with documentation about himself. So, please send me a email with the informations from 7255. So long Holger

If you can see an email button you can. Some people don't want any contact and therefore the email possibility is switched off.

Larsholt tuner module

Anybody know how to convert a Larsholt tuner module to the American FM band (88 to 108 Mhz)? It seems to tune from Ch 5 (US) sound to about 100 Mhz. The only identification I have is a sticker that says AREF 7604 and Made in Denmark. It has 4 IF cans. I tried playing around with the tuning voltage but that didn't help. Do I need to change the varactor diode? Thanks.

I've been bequeathed a lot of audio gear and in amongst it is a Larsholt 7255 FM Tuner. It doesn't work so am looking for any information/ assembly instructions for this so i can have a crack at getting it going. I notice from earlier posts that peranders has some info, but as that was a few years ago now I am hoping that he is still around to help out.
The module is on a PCB which I assume was part of the original kitset and there is evidence of some 'tweaking ' of coils & trimpots iside the can as all the seals are broken. Any help would be greatly appreciated. Thanks Mike
