When the power switch was pushed there was initially no The receivers had a protection relay between the amp outputs and the The most horrendous of these was the intermittent loss of signalįrom the amps to the speakers due to corrosion on the contacts of the protection Often had a problem with corrosion on the silver contacts used in their The relays in Marantz receivers (and likely the amplifiers) of the 2245 vintage and later I use it to catch DXĬonditions on FM, though it's detuned at 88-108 MHz, it still does a very credible job The tall pointy antenna above the APS-14 is an AEA "Isopole", a 144-MHzĭesign that is omnidirectional and listens at the horizon level. Should give you an idea of the scale of the antenna against the tower, etc. That's my friend Mike on the tower below the antenna. If you click on the thumbnail on the bottom, you can see a 4x version of the antenna Need a pretty amazing antenna to pull a microvolt or two into your FM front end! Reception are just about ideal, but the point is that at 179 miles, you I live on the plains, so terrain conditions for this kind of distant station Afternoons, skip does tend to come in and whack KMHK upside the head, but

That's a full quieting signal about 99% of Reliably, as you can see at the right top. Miles (see map here) away in Hardin, Montana fairly The antenna is an APS-14 (they now sell an APS-13) It is a large, 14-element,ĭual-driven director-only design that pulls in KMHK, a classic rock station 179 air What it can hear (and I know the 2130 is operating perfectly!) the Signal Sleuth really makes a difference in The 2130 has "that sound", but the RF front end technology is gettingĪ little old in the tooth. Preamplifier to "front-end" the whole thing. Which is about 16% more sensitive, with a Magnum Dynalabs Signal Sleuth RF The picture at the right shows reception on a 2285b receiver now I use a 2130 tuner, Over on the immediate right at the bottom is the antenna that I keep on the Marantz Indicator you need, be sure to tell the Marantz representative that!įinally, an FM Antenna that is really worthy of our babies! Requirements for the bi-pin stereo indicator lamps. To replace the HA-1156 mentioned above! I do not have a source or details on the current Using the sameīi-pin lamp overloads, and can blow out, the stereo decoder IC. Lamp than the other indicators in circuits using the HC1000401 PLL IC. WARNING! The FM stereo light requires a lower current Marantz still sells those for a price ($3 - $5 each) The factory specifies bi-pin lamps rated at 6.3V 40 mA. the interval to the next required replacement will likely be much longer!) Or else replace them all (a better idea,Īnyway.

In thisĮxample, you could put two of the old bulbs in series with each other, and then two sets Non-equal voltage divider which in turn causes a variation in brightness. (which means that the internal hot resistance is different), and so you'll have a The load won't be even, since these aren't the same current ratings When you replace bulbs, don't put the new bulbs in series with the So a 6-lamp panel that is completely dark most likely has 3 goodīulbs still in there. SoĮach two bulbs are in series, like an old Christmas lamp string. Hint: Marantz has a tendency to wire the fuse panel bulbs in series pairs. I have seen melted plastic bezels from using full sets of I don't know how much extra current is availableįor the lights on a per-unit basis, though I know of no case where this has caused a problem Note that the extra current requirements can add up, as can the extra heat, whichĪmounts to a twenty five percent increase think twice before replacing anĮntire set with higher current bulbs. Make sure you know whatĬurrent you're getting - 200 ma or 250 ma. You can also find these on EBay search for marantz lamps. The factory specifies an 8 Volt 200 mA lamp, but you can buy the 8 voltĢ50 mA "fuse type" lamps, part no 070-120. They can get replacements - I saved a 2240's FM stereo capability with this part!
