I've been thinking about getting a Dolby B decoder and found this for $1.99 plus $11.82 shipping (=) $13.81. For less than $14 I figured it was worth the gamble. I can find no information on the Internet.From the picture you can see Dolby calibration is adjustable for both recording and playback. I don't see a Dolby tone generator, but Barclay-Crocker tapes have Dolby test tones on them. I guess I could use these?
Also some bad news to report. My car was broken in and my Kenwood Cassette Deck was stolen. Any suggestions for a replacement? I would like frequency response 20-20kHz at -20VU, Dolby B and 70us EQ for my audiophile Cassettes.
I thought cassette decks were safe from criminals. Either they thought it was a CD player or some criminals still like cassette. Bad thing I've got to replace a window too and my deductible for other than collision is $500.00. I'm stuck for the whole thing myself. Anyway any thoughts on a good cassette deck for the car?

Follow Ups:
I have owned two car cassette players that were noticeably better than the stock OEM players. One was a Nakamichi I bought in 1987. I don't recall the model #, but it had dolby B and C, but was a head unit only and required a separate power amplifier. The basic Nakamichi 4 channel amp was fine. This deck was unidirectional. As I recall it was quite a bit more for the auto-reverse version. I think I paid about $700 for the deck, amplifier, and installation. It worked flawlessly for 7 years and was working when I sold this car. I was tempted to remove it.I also enjoyed a Sherwood cassette receiver bought in 1993 as a replacement for a Honda unit that died. It also had dolby B and C. It had a line input jack on the face (useful now for iPods). I think it was about $230 for a model change closeout unit including installation. It is still working, although the volume control is scratchy and intermittent. I bought a "new in box" replacement unit on eBay several years ago, but have not installed it as I don't drive this car much any more. I was very impressed with the build quality and sound from Sherwood equipment of this vintage. I didn't see any similar ones on eBay today.

It does have the Dolby tone generator. You record the Dolby Tone and adjust record calibration for 0VU and then play it back and adjust the playback calibration for 0VU and your done.I had to do with the output of my Nakamichi cassette deck as my Reel to Reel is in the shop. So when I get the Reel to Reel back I do the same to set up for it.
I used "The Missing Linc" Sheffield Lab / Nakamichi Reference Series (1:1) Real time duplicated TDK Metal cassette to compare the internal Dolby with the Marlux as it has a lot of high percussion instruments extremely well recorded. The Marlux was a bit better on high frequencies and was just as quiet.
Next I tried a non-Dolby cassette: Dave Brubeck's Time Out on Columbia Legacy the 1997 Digitally remastered version. Excellent sound even though it has audible tape hiss. The pass though output on the Marlux with Dolby off was identical to the output of the Nakamichi with Dolby off.
The unit measures 13 3.8 X 7 X 3 inches. My best bargain of the year! Less than two bucks for the unit, $13.81 with shipping. I am thrilled I will be able to correctly decode my Dolby Reel to Reels.

I have posted before but : I've bought several dolby units off of ebay looking for a neutral sounding ( or as little sound as posable ) and have a pile of them to prove it. I was looking for something to decode my BC tapes as well and because of the age of the units, they all sounded muffled and distorted ( bad caps and aged wave soldering are maybe to blame?). I never tried a few units ( Nak nr200, Advent or the pro units that Canny mentioned) but being a cheep skate, I just kept trying the ones I'd win for under $25. I came across a unit I'd seen mentioned just one or two times from a British company called Integrex. I also found out that BC actually sold them to be used with their tapes. There are 2 different models, one that encodes and decodes and the one that I have ($10 on ebay) that is decode only. It is almost totally transparent is small and very well built ( high quality electrolytics, resistors and hand soldered). I never got around to rebuilding any of the other units I have so I don't know what their potential are but if you can find an Integrex, I think it's what your looking for. The most I've seen them selling for is around $40 from some online audio stores for the encode/decode units. Try Googling dolby noise reduction .
It looks almost new inside and out, I was afraid it wouldn't work with a BIN of $1.99. It looks really pretty too. See above post for my impressions.
