* Thick, heavy aluminum faceplate and overall very substantial construction on essentially the same chassis for all three models * Patented "Quieting Meter" that measures the signal-to-noise ratio of the received Here's Eli: "An eBay listing said that the 14/15 had the first PLL MPX in a production tuner, but I don't know whether this is true. The Citation 15 can sell for almost anywhere from $50-200 on eBay, depending on condition to illustrate, a decent one with a wood cabinet went for $64 in 3/09, but another fetched $240 in 5/09 (go figure). *Very* nice design and build quality." Nice Citation 14s usually sell for $140-260 on eBay, but $75-100 is more likely for cosmetically challenged ones. The PSU uses a multi-section electro which could be hard to source these days. The audio sections of the 14 use a large number of 2N3417 transistors these days I guess you would use BC639. You were expected to buy the whole 'FM front end' assembly for servicing purposes. The RF board with all those LC filters is completely sealed inside an enclosure that can't be removed without removing another PCB or two first, and HK doesn't even list the transistor types. I imagine the 15 does too, as three PCBs just isn't enough. Our contributor Esmond adds, "The 14 has three circuit boards on the chassis top and another three on the underside.

The superb owner's manual contains the instructions for kit assembly as well as operation. Be careful and know what you're buying, because the DH-330 was available both factory-built and in kit form as model no. The headphone jack connects directly to a dual 10K volume control, and then back to an op-amp." The DH-330 can sell for almost any price on eBay, from under $50 to over $150, and the record low and high are $25 in 10/07 and $175 in 1/08. Yes, it does have a headphone jack however, it is intended for use with high-impedance headphones, not for use with 32-ohm or lower phones. And Ed adds, "A word of caution on the DH-330. It does a pretty credible job in most situations except for a strong station next to a weak one." Thanks to Joe for creating the front end schematic linked above. Our contributor Joe says, "In comparing the Hafler DH-330 against my other tuners/receivers I find it just a little bit lacking on front end selectivity.
I did not look at the audio but one can, from experience, assume that an increase in size and type of capacitors in the audio path reduce bass distortion due to phase delay."

The selection process requires a good scope, an FM signal generator for the sweep signal and another FM tuner to provide a source for the 10.7 MHz signal required to pick out a good one. The transistor amp is easy enough but the ceramic filter is another story, as filters can vary significantly in characteristics and must be selected.

This mod is not extensive but does require parts selection. The DH-330's selectivity can be improved with the addition of a ceramic filter IF amp at the mixer output. Our contributor Ed (VE) says, "The Hafler tuner is a computer-controlled unit with varactor tuning, 3 in the RF and 2 for a buffered local oscillator. The only Hafler tuner that is reputed to be halfway decent is the very common, ugly-looking FM-only DH-330.
