All about vintage FM tuners

Featured

In the 70′s I had a Marantz 2270 receiver, Marantz Imperial 7 speakers and a Dual 1229Q (I never did the Quad thing) with a Stanton 681 EEE cartridge. It was my first stereo and I didn’t know a whole lot about hi end audio, I just knew that I liked the way it sounded.

Fast forward to today. Just to see what they are like I got an ‘old school’ tuner, a Kenwood KT-8300. I was amazed at how great it sounds.

I would like to know more about ‘old school’ tuners and there seems to be quite a bit of interest so I created this site.

The focus is analog FM tuners, AM too. Vintage stuff, before tuners got to be all digital. It is not intended to be a “Brand X is the better than anything else site”, just a place for people that particularly appreciate vintage tuners and may or may not (but probably will have LOL) a brand they like best.

Anyone is welcome to join and post but you will need to register first. Please keep it polite.

Tell us what vintage tuners you have or would like to have, what vintage tuners you like. Modifications you have made or heard. Ideas you have. Why you like vintage tuners. Post pix too!!

As this develops we can create sections the have a specific focus, maybe a discussion forum, suggestions welcome.

Have fun!

Tuner Heaven site update 01/06/2013

After blundering my way through the process, the Tuner Heaven sites are now all associated with the main site, Tuner Heaven, as a network. This will make administration much easier. I need all the help that I can get. :)

I had hoped that in creating this network the process of registering would become easier as only one registration would be required for all of the sites except for the Capacitor site.

Unfortunately the registration mechanism has disappeared completely. LOL I will try to find it or install a new one today. This should provide a common login\user name for all of the sites other than the Capacitor Forum. It is phpbb rather than WordPress so I don’t think that there is a way to do it.

Please use the same user name when you register for the Capacitor Forum. Thanks! SteveJewels

 

 

Bateman capacitor study

I am very interested in the sonic qualities of vintage tuners. Given their age (at least 30 years or or nearly so) the capacitors in them may need to be replaced. Much has changed in the electronic components industry and in the Audiophile arena so it is at least possible that replacing the capacitors in vintage audio equipment may provide benefits.

I have several tuners that will be receiving ‘capacitor enhancement’ to coin a phrase if I may do so. I have been Googling capacitor information and reading all that I can as to what, where, when, if and why to use or not use certain capacitors.

This includes replacing caps because they are old, because of changes in technology,  because of changes in manufacturing techniques, to restore original sound quality, to improve longevity of the tuners, to improve the electronic performance of the tuners and with any luck, ultimately, to improve the sonic qualities of the tuners.

The articles that were published by C Bateman in Electronics World starting in July of 2002, while perhaps not the final word on all of these topics, certainly represents a cohesive and comprehensive jumping off point for investigating the above mentioned reasons to replace caps, or not.

In reading through the articles I realized several things:

1. Bateman began his investigation with an obvious bias. As an expert capacitor designer (which I am convinced that he is, not that he required my endorsement LOL) he was very skeptical that any such sonic difference existed.

2. His position was that any perceived sonic difference from one type of cap to another, if any existed at all, could be quantified empirically.

3. That there are many people that do not have the background to receive the fullest value from the papers he published. That is to say that even though they have the ability to discern even very subtle differences between two systems that are not the same, they have not had the experience performing the measurements that Bateman refers to or have not studied some of the materials or methods he talks about. Nor do I claim that I do.

4. That his conclusions are not clearly and cohesively stated.

5. That the path he took during the course of his investigation while excellent, was a bit circuitous. Since the papers are sequential and build upon the preceding paper it might be helpful to have a ‘map’ of the route he followed.

So I was having a hard time following the papers and found it necessary to make notes so that I didn’t get (too) lost. LOL It occurred to me that others might appreciate a ‘Cliff Notes” version of the Bateman articles.

I am going to open a Bulletin Board section to Tuner Heaven where I will post my notes as well as my thoughts on his, and perhaps other, investigations on capacitors, hoping to take care of #5 above.

I will also do my best to clarify items 3 and 4.

I too have a bias. Even though I do not thoroughly understand what sonic differences may occur, with the use of different capacitors , I am inclined to believe that there are sonic differences that can be discerned.

I am hoping that by providing what information I can and providing a focused forum and repository for that information will foster ongoing discussion and investigation and little by little, improve our understanding of the effects and benefits of replacing capacitors.

I welcome all contributions whether they be additional viewpoints, corrections of my errors, other technical investigations of capacitors and most especially questions.

Tuner Heaven site update

Tuner Heaven runs on WordPress which is blogging software. It takes care of a lot of the coding and makes a pretty nice website.

Since I am an electronics hardware guy and only do and learn pretty much what is necessary when it comes to software. WordPress makes it pretty easy for me to do that.

The people that have registered for Tuner Heaven are only registered for the main site. Several of you have asked for a global login, one that doesn’t require a separate registration for each sub-site for example the MARANTZ section.

I did some Googling and found that WordPress has a ‘muilti user’ optional install that will allow all of the different sections to function under the main section and will not require multiple registrations. So if you are interested in say, Kenwood tuners, FM Antennas, and Modding, you can post in all 3 sections with one registration and just one login and user name.

Since I am a hardware guy it is probably going to be a bit more difficult for me to understand the instructions and take longer. I am going to try to have it complete buy Tuesday evening, January 1st.

If you have already registered  am hoping that your registration will carry over and that you will have the new functionality. Plan B is that I will restore your registrations after I complete the conversion. Plan C is that I will profoundly apologize and you will need to re-register. :)

 

What you will find here

This is the main section of Tuner Heaven. This is where to find general information on all aspects of vintage tuners. The information is of a general nature and will apply to various brands of tuners and to FM radios in general.

There are additional sections of tuner heaven that focus more on specific brands of tuners, Kenwood, McIntosh and Sansui in particular.

Initially this was to be a site that emphasized Kenwood tuners but there are just too many excellent tuners around so we have expanded a bit and will add more sections as they are requested.

If your favorite brand of tuner needs to have a section, drop us an email and it will happen for you.
