Thumbs up Recording hiss.

Immediately, 2 things come to mind. Is audio hiss there all the time, or, only when needle is on your recording playing it?? There could be one of 2 things wrong. 1 an amplifier problem causing the hiss. May be a noisy tube. or, 2 your weight of recording cutter is too heavy. This is usually adjustable via a screw near front of top of recording arm. You also don't want "holes" in your recording. These are spots where groove cutting stopped, and started. Usually caused by combination of too much weight, and worn recording needle. I assume you also know that the flat spot on recording needle was intended to be where screw on front of arm held it in. Glad to see someone else is interested in recording. This can be fun, and the results are rewarding. The last disc recording that I did as an experiment 21 years ago I reccorded a favorite 2 min. cylinder recording of mine. Still have that disc. Can you tell me where I can pick up more cutting needles, and good aluminum shelac blanks? 10", and 12". Magic eye tubes, by the way, are not terribly accurate at telling volume.

We will have to try it again...thanks for suggestions. Unit works O.K. on playback of commercially recorded records. I will find out from my business partner on where we got our supplies from...seems like we were able to get needles and different types of discs from the person who rebuilt the cutting head.

Your recorder

Another question comes to mind. Did you re-build the amplofier? The old caps are leaky, and could conceivably be causing your immediate problem. I'd re-cap whole thing, and put in neww electrolytics, as well, to bring power aupply up to full potential...... Now, as for quality, how well is it actually playing? If un-rebuilt, it can't be great. Some people think that if it "makes noise" it's doing great...As for me, Knowing what the full potential can be, I opt for bringing them back to factory specs. So, let's all have fun with "our toys". But, as when younger, these gems of the past need proper maintennance.

Talking Shop repair

How did your shop repair go? Any luck?
Need help on a sick Recordio portable. Anyone got one with rough cloth coverred case they want to get rid of? Mine appears to be late 30's, or early 40's. I'm missing all hold down screws, mike, I have a broken wafer switch, and it's a general mess. This model does use an eye tube, missing, but no radio. Bill Cahill

We haven't worked with the Airline disc recorder in a while...we did repair all of the trouble sources such as old caps. Radio and playback work ok. We will have to do some more tests on it to check the recording quality again.
