Same the Pioneer D500 I have. Identical! And the Tascam DA-20 also. It's a good thing because I have a lot of spares for my machine. Other than that...I have to admit that it's a very reliable machine.
Your right it looks just like a Tascam DA-20 transport...PS i found out what was bad with the DA-30 was working on BAD HEAD found a new old stock one (LUCK)
Just placed an order with Digikey as long as my order is under 1 pound shipping is 4 bucks for first class mail (USPS Ground Advantage now) takes the sting out of placing small orders. As someone who has shipped items to Canada before the rates are obscene.
@@12voltvids That's cool. One advantage that DCC does have over DAT is that the transports are far simpler in design since they are stationary head machines. And they are backwards-compatible with analog Compact Cassette. But the format doesn't have as high of performance as DAT does in terms of sound quality because DCC uses MPEG-1. But as many, if not all, of these units also use SMD-type electrolytic capacitors that just like to spew their guts out, you know exactly the kind of fun you may be in for when attempting repairs on them.
@@Watcher3223 no advantage at all. The chance of a misaligned head on dcc was magnitudes greater than dat because they had moved back and forth every time you hit play and stop. every time you loaded that there was a chance of a misalignment especially if the pressure pad on the back side of the tape was slightly worn. Also the heads being a thin film sputtered laminated head wore out fast and a slightly worn pinch roller that skewed the tape made them unplayable. Technics recalled and crushed unsold units from stores. We had a few at the shop one on display and a few to sell. 0 sold and Panasonic took them all back and scrapped them. They offered them at 50.00 to anyone that wanted one but none of us were that dumb. (I already had a dtc75es DAT which is still functional. ) Dat uses auto tracking like 8mm video. You have to be way off before it won't play. Uncompressed is also much better.
@@Watcher3223 I remember having this exact argument with a guy i know that was studying to be an electrical engineer. He was all over DAT with the rotary head being junk and dcc being superrior. In fact he was the only person I know that ever bought one. He recorded a whopping 5 cassettes in total and then he realizes they format was garbage. They play fine the first few times. Once the tapes start to wear there is a huge bit error rate and got help you if the tape stats to stretch. He stopped using it after about a year and made the move to minidisk. I ran into him at a party i was at probably 20 years ago and I was giving him a bad time as all my dat tapes still played perfectly.
Question: I have a 1990 Panasonic full sized VHS camcorder model AG-190. Everything works on it, except when I record to tape, it only records in black and white. The composite out from the camera shows live color on a tv, but recorded and played back tapes have no color to them on the cameras VCR or a known good VCR. Any ideas? I'm thinking caps or a loose connection, unless you know of a common problem. Google is usually my friend but not today.
You need to understand how color is recorded on consumer video equipment and this includes VHS betamax and 8 mm. the colors actually separated from the black and white of luminance information and it is converted down and frequency and that's recorded under the monochrome or black and white picture information. It's converted down by mixing the chroma signals with a down convert frequency and then recording this converted color to the tape. On playback the reverse is done it mixes the playback chroma again with the conversion frequency to add the signals together and move the color back to where it belongs at 3.57mhz for ntsc. this is a very complex process that is handled by the chroma icy and that is likely where the problem is. It doesn't mean that it is the chroma Ic it could be capacitors on the chroma Ic or in related circuits. Panasonic and Hitachi had a nasty habit of using these composite modules which were a little circuits that were basically built on glass and covered with epoxy with discrete components and the capacitors were the nasty surface mount type. these were very poor designs that Panasonic used to use a lot in their AG series so-called professional line use them. It's one of the things that made the AG 1970 for example such a big piece of crap. Back when the parts were available they were ridiculously expensive 70 to $80 for a module which made then an economical. Panasonic wasn't the only one to do this. JVC and Sony did it too. Songs are usually in small plastic orange colored modules that were potted in epoxy. the reason they did this was to try to stop others from copying their circuits so they part of the many epoxy to make them more tamper-resistant. the thought was if you tried to say put them in a type of solvent to remove the epoxy or an acid to remove the epoxy that you would destroy the circuit in the process of trying to de pot them.
so you would recommend not opening the camera, and keeping it as is, is what i'm taking away from this.@@12voltvids I appreciate your insight and backstory to the camera. I had a panasonic newvicon camera that had a stuck iris, and still wouldn't work unless I cut a hole in the side of the lens and manually operated it with a paperclip. I ended up saving the board with the tube and scrapping the rest of the camera in hopes of one day doing a project where I could capture a video signal from that board.
@@McFixStuff you can open it if you want. There are a bunch of surface mount electrlytics that need replacing. If you want to replace go ahead. If you are thinking if getting someone to do it for you they will charge more than it worth or outright refuse because those with knowledge know that it's a temporary repair.
@@12voltvids So i opened up the camera and found a fold out board that when I google one of the ICs it shows its for a panasonic vcr. On the back of the board I notice some corrosion around a capacitor labeled C1, and it looks like there is a ?transistor? labeled Q8 that is kind of white from the corrosion. Unfortunately there is no service manual with a wiring diagram easily available online, but I'm going to assume thats the culprit, as when play a VHS tape with color, the colors somewhat display and when I touch that spot with my finger, the colors go away. I might take a gamble on it and replace the stubby capacitor. You wouldn't happen to know a good spot to find a wiring diagram, or maybe another camcorder that shares the same component where I could look at the wiring diagram?
