Magnum Dynalab 205 FM Signal Sleuth focusing bad?


i recently bought a used Magnum Dynalab Signal Sleuth (model 205). and it has a BIG problem... the focusing control is not working in the right range. for instance, if i were to be listening to the channel 91.5MHz on my Yamaha TX-950 tuner, i would have to set the 205 to about 95-96MHz. so, in other words, it's off by about 4-5MHz. and that is a terrible problem if you want to listen to say, KROQ, which is at 106.7MHz... cause the knob doesn't go above 108MHz, so i can't even use the 205 with that station!

also, another problem is that the gain control is labeled wrong too. it has the 0db position at about 10:00. however, the actualy 0db position is at 12:00. now, this might suggest that the unit is capable of more boost, but somehow the knob or the circuitry it's associated with isn't going high enough.

i dunno....

the guy i bought this from said he sold 2 other units previous to mine, and both had the same problems. so, it seems they're all like this......

you guys have experience with this signal amp?

My 205 is almost 20 years old & it still works just fine. On the unjt you bought, it seems that someone may have forced the knobs, or removed them & re-installed incorrectly. The anecdotal reports sound like user errors - do you know how to peak tune the preselector? Spend the lousy $25 & have it checked out - that's a giveaway.
