Which funds have done best since Lehman's collapse? Choose from TVs from the most popular tech and electronic brands to find one that delivers the stunning graphics and sharp picture quality you need. The key factor of a 4K TV is its screen resolution, which is x pixels or 4, pixels visible on the screen. This is more than four times the amount of a basic HDTV, which has lines of resolution.

UHD TVs actually have a slightly lower resolution of x pixels, which is barely noticeable to the naked eye. You can get deals on sets in a number of different sizes with the majority falling between 40 and 85 inches or more. When selecting a 4K TV, make sure to have plenty of room to properly view the set.

On the smaller end, you should allow for at least 3. A tuner with 3 or more filters can almost always be made more selective with a filter mod, and the most selective tuners use 4, 5 or even more filters. Would-be filter modders are cautioned that while replacing a tuner's stock filters with new narrower ones will certainly improve selectivity, if the new filters have not been professionally measured and matched, there is likely to be a noticeable degradation of audio quality.

Particularly when changing filters in a digitally tuned receiver, one should ensure that the new narrow filters are centered right on An alignment can improve a tuner's weak-signal reception, distortion, and stereo separation. Also, in many cases the tuning dial reads incorrectly, and an alignment solves that problem although it should be pointed out that a well-calibrated tuning dial does not necessarily indicate that the tuner is properly aligned.

Setting the tuner's detector correctly can also improve reception of adjacent-channel stations. If one listens primarily to strong local stations, it may not be apparent that a tuner is out of alignment, and a misaligned tuner can have sensitivity as high poor as uV and still sound fine on locals. With a good alignment, the sensitivity of many top tuners can be improved to 1. Then a bunch of BNC cables, test leads, probes, etc.

In some cases, you may have to build adapters or probes from scratch or otherwise improvise. Procuring the equipment is one thing, and figuring out how to use it successfully is another. Many people could do it with proper training and help, but it is best learned by observing in person, like learning a trade, rather than by reading how to do it. Usually the manual for the stereo generator is a good starting point.

Our panelist Bob discusses alignment techniques in our FMtuners group in the series of posts beginning here , and here is a useful discussion of alignments of Scott tuners, most of which have broader application.

When selecting a shop for tuner modifications, repairs, or even just a tuneup, ask what kind of test gear they use to complete the final RF checkout and alignment. We believe it is critical that RF mods, repairs, and alignments be fully measured to ensure that the tuner meets or exceeds factory specs as set forth in the service manual. This critical measurement should be in addition to the final listening test. January update Bob suggests the following for those who want to learn to do their own alignments and repairs: One, to give people a map or learning process.

Second, to help by identifying the material that should be covered, and key phrases to be used in searches. You should be able to get all the info you need on the internet.

To understand an FM tuner, you need to understand FM. Keyword searches in places like Wikipedia, or in general on the internet: Questions you need to understand: What is the FM deviation standard?

Why are pre-emphasis and de-emphasis used? How is an audio signal's amplitude represented in an FM signal? What is the standard for stereo pilot frequency and level?

How does stereo multiplexing work? Next, understand how an FM tuner works. First, though, separate the learning process by the major technologies for vintage tuners: Start by reading the theory of operation, then the tuner block diagram, and identify the above sections on the block diagram. Make sure to include all three technologies if you want to get the full spectrum.

Then work at identifying the above sections on the schematic. A really good read on the state of modern tuners, including explanations of many sections above, can be had by reading David Rich's two FM tuner articles in Issues 23 and 24 of the Audio Critic, located here.

Completing this self-study exercise should give one the background needed to start aligning and repairing FM tuners. See our DIY Mods page for information on modifying tuner audio sections. This small PCB fits in place of a standard ceramic filter and provides sockets for two filters plus some additional IF amplification.

We have heard some horror stories in our FMtuners group about tuners that Ken has held onto for YEARS here's just one of 'em, part of a long message thread , and obviously he has forgotten that reputable businesses have an obligation to communicate with their customers.

We're going to opine, without malice, that there must be some serious mental issue here, based on the number and severity of the complaints and Ken's utter failure to respond publicly to them. With so many other good techs recommended above, you'd have to have a screw loose yourself to send your equipment into the black hole of Ken's shop.
