Incomplete video. You have missed showing removal of front plate which will reveal a screw on the right side of the mechanism screwed in from the front to hold the mechanisim from its front side which must be unscrewed after removing the front plate. This mechanism is NOT designed to be easily user serviceable by pioneer.
Hi. I have one of these machines. Looked after well and greatly enjoy playing it. However one of the input nobs is really turning more loosely and sounds crackly and scratchy when using to adjust recording. Any advise on how I could remedy this.
Hi! Thanks! I don’t think is CCP, since is DC plasma, not RF. If I find the time I would love to do a followup of this video (I’ve just upgraded the secondary pump to a turbo pump). In that I will add a materials list too.
.. This is why they put inserts on mixing desks or just record on computer and send audio onto tape there is no magic sound on the Tascam pre amps. Things get interesting if you record smpte on to one track from reaper daw and then sync reaper from your A-3440 so reaper plays or records when you start the A-3440
I have a 2213 fully functional. But I couldn't remove the power supply shield, the rear screws T7 didn't come, I would have to drill the head and replace them afterwards. Cheers.
I also changed the two pin mains input to three pin and connected chassis to mains earth, also changed the mains protection rifa cap at the mains connector, if this cap fails the chassis can become mains live, also changed the three motor control capacitors, the three big aluminium caps behind the mains panel.
hello, I have a B780 which was completely overhauled in 2016, and which works wonderfully. For a month now when I turn it on it works perfectly for 35 to 40 minutes then a fuse blows and the sound is full of distortion. I turn it off letting it cool and I can listen to it normally again for 35 minutes until the fuse blows again! what do you think could be condensation or another cause of the problem??? thank you in advance
Hi sorry for the late response. It could be a bad capacitor that is turning into a resistor, thus heating up and then shorting a part of the circuit, but I suspect there’s something else in your machine. These amps are exceptionally well constructed, but the board assembly, although very easily serviceable, means that you’ll have a ton of contacts that with time can oxidise and not make good connections anymore. They sometimes can move a little and short something too. On the unit I had there were a lot of contact problems due to bad storage conditions. In your case it seems that a component or some contact between boards or components may heat up and then short something somewhere. I would reseat all the connectors and boards and test the unit taking measurements of temperature around (even better with a thermal camera). Hope it helps!
I hate when people say you can't master a song on 7 1/2 ips. You can! And it sounds amazing when the machine is calibrated tho. It may sound different to a 15 ips machine, but the B77 is super good machine. Even A77 can handle that quality imho.
Thanks for this video! I have a Tascam 48 OB and channels 3 and 5 went out randomly and am pretty sure it is due to having to move or “scoot” the unit over while recording one day. Luckily i also have a parts unit that I can swap a card or two out with... thanks again, it was helpful. Cheers from USA!
I have a quick question, when using the bypass resistor instead of speakers, does hooking the DI Box add additional impedance? It seems that the resistor and the DI box together would have their own impedance.
omg. Don't care about the noise. Tape sounds so much better. I don't want to go down that rabbit hole, but this video brings me closer towards getting a reel to reel machine.
Do you know what type of open reel tape deck Scully was using on the X-files Season 2- Episode 1 at the end of the episode? Is it a Tascam tape editing system? Show was 1994.
I guess you found the other 3 Rifa caps and replaced those too? 1 is behind the iec power connector, 2 others on a small pcb behind the reel speed switch…. I found out about these when the one at the power went up in a massive cloud of smoke :(
Thank you very much. I just received this model that I bought on ebay. The belts need replacing so I've ordered them and will try to replace on my own. Your video was very informative and I'll watch some more.
mote to all out there on the use market place over the years i have worked on alot of this model i will say all the decks i have have something not right as long as they play record on the same deck you will be ok just don't record on yours and try playback on the same model you may find what is not right on your deck i have alot of tascam 38 myself over 10 breaks start in the main logic pcb and the same kind thing over the pcb they have lasted along time 40years is good for the deck the teac 80-8 are tanks have 3 myself i do alot of audio moving of old tapes
I have a b77 MK2 and I absolutely love it best tape deck ever. Mine was factory serviced and calibrated and I also found a new old stock brand new tape head which I had installed in calibrated It's a fantastic machine You're going to love it
@@dubdoodle7191 no not crazy at all I saw a video of a guy who drilled a hole someplace in the unit where he could reach the screw that adjusted the azimuth of the tape head so he could put a screwdriver in there and very easily turn and adjust it based on the tape he was working with. But I am depressed about is the fact that there are no new companies making reasonably priced real to reels there are a few companies making them but they want ridiculous sums like $20,000 which is absolutely ridiculous.
Strange that the meters change position when you turn at the output knob , I've never seen that before , I mean where is the reference . Normally only the volume changes when it's connected to the amplifier and the meter output in the display stays the same . Also strange that no-one below comments on that
Awesome track! I'm currently checking out and auction for one of these machines, I'd like to get a multitracking deck to work with, as I do already have two pretty nice quarter track stereo decks (AKAI GX-600DB and Sony TC-630). Love doing all sorts of experimental sonic stuff with them. Excellent video as well!
This is an excellent machine, very good and sophisticated mechanically and electronically, I have been very attentive to the entire repair and you have done a wonderful job, now, about TASCAM, why in 1/2" does this brand use a pulley to drive the steering wheel? I cannot understand this, the belts are good in the sense that they transmit less vibrations to the shaft and the tape, but it is a totally unnecessary added factory problem when the correct thing is to mount the shaft in the same motor and you eliminate parts and risks of disasters. Very good video.
Hey, sounds great, but the genre and style of music does not suit the A-3440 ! I had one of these in 1978 when they first appeared and music was far less raunchy. it would be nice to hear it in the style of the day. Great though.
I don't have a B77, but I do have an A77 MKIII which has been in the family since 1972. I have noticed from your video that the under-side of the boards are much better than those from the A77 series.
Very happy to found this video, thanks for your knowledge and information about this beautiful tape machine, I'm a lucky owner also and the machine needs some love, you made it more relaxing for me to start the restoration.
Your English is very good. I can appreciate this I because I am a student of both Spanish & German. Have you ever visited the USA? Every once in a while you pronounce a word like someone from England. Most of your speech sounds like that of an American pronunciation with a German accent to me. I was born & raised in Texas by people born & raised in Texas etc., etc. I live in the Texas hill country that has a lot of German immigrant influence.
Hi! Thanks for the nice comment, I really appreciated it! Actually I’m from Italy! But I know, I got a bunch of influences in my accent, sometimes it’s a bit confusing :) I’ve been to America, but I never had the chance to stay enough to visit it more.. I love America so maybe in the future I’ll return for more time! Cheers! Dave
Hi! Ebay is the answer. I have also the original ones from Teac, if you want to be sure, get those. They’re a bit on the expensive side, but they will surely fit.
