Did not even know that thing existed, so many parts and components, must have been a bloody fortune back in the day.

I love the smell of old electronics

The HK 705 series was used in American Psycho, except for the CD player which was a Pioneer PD-340.

This was always such a unique and interesting design. I always felt like it looked special and different from the rest. The one thing that strikes me as odd is that the eject mechanism seems so fast and clunky. It should have been a slower, soft operation. Great job getting this sucker working again!

I definitely enjoy the videos when you talk better. Are brains think alike and your sense of humor adds a lot to the experience

That coil/spring loading mechanism is criminally done.

The Fresh aroma of new arriving audio equipment. I've watched this several times. That always makes me laugh. I totally relate.

I have that same deck, along with 720 turntable, 710 tuner, 725 pre-amp, EQ-7 equalizer and the 770 amp. Still working pretty well.

I love how you very nervously pressed the power button. That exactly my technique too, even after I've repaired something, lol.

It is nice that ypu started to speak in your future videos.

Crazy loading system but nice eye impression . I brought to good operation two Telefunken cassette decks made in 1979 and then made experimental music recordings from radio. Used cheapest maxwell tape available in ninetees - ferro type, almost not used, no noise reduction switched. The result in my system and wtih my speakers is as good that I do not know how I will listen now to my CDs - I like more sopranos from deck.

Sounds like the heads are in correct azimuth and good condition.

nice deck. Awesome. Thanks for the good work.

Thanks, for cleaning the heads, the small hatch on the top of the deck that I replaced would probably work, but that's a good point as far as head demagnetizing, since I'm not sure a demagnetizer would fit through and reach the heads.

Das muss 💘 sein...... Was für eine Reparatur

my brother in law had the 3 head version of this loading system. i recorded lots of his vinyl using it.

éste modelo no lo había visto, yo conocí HARMAN KARDON a partir del TD 4200, y TD 4800, y la última creo, no sé exactamente pero creo que contaba con el Dolby S, aunque reconozco que los dos decks grababan muy bien 👍

cool deck man, good job on the repair. i would be a little concerned about that resistor though; usually resistors don't "just blow up," especially such modern ones. high probability that there was a short in there somewhere, or that the motor itself is shorted

@@briangoldberg4439 The stall current of a typical DC motor is several factors higher than the free running current. The resistor might not have been designed to handle it. If this was indeed the case, the failing resistor might have saved the motor from becoming defective (as the insulation of the motor coils can eventually melt due to the excessive current).

@AnnaVannieuwenhuyse

@@briangoldberg4439 the mechanism behind this (which solwidotnl enlightened you to) is that the electromagnetic happenings cause the impedance to rise after the initial rush-in that causes the motor to start. They are self regulating in this regard. When they're stalled, there's no electromagnetic flux being dissipated though motion, which causes no change in impedance and... rather quickly a change in physical structure instead :)

So good !

Love watching repair videos. I have a Sony Elcaset that could benefit from your talent. Would you be willing to take care of it for a reasonable remuneration of course ? Thank you

That resistor is probably used to drop the voltage going to the motor so the action of the drawer or tray mechanism isn't so fast and abrupt. I would put a substitute back in place for sure. The other question is why did the 1st resistor blow in the first place? There must have been a lot of current being pulled by the motor at some fail point for the resistor to smoke like that especially since the motor is only intermittently used. What a nice unit. Great job!

@@HifiJelly I might be tempted to put in a self resetting fuse ( a polyfuse/PTC) in place of, or as well as the resistor. If you don't know the original value for the resistor, then just use a polyfuse.

@AndyHullMcPenguin

Жыл бұрын

For the fuse value, measure the current when the motor runs normally. Double it. That should put you in the ballpark for a suitable value to limit the stall current of the motor. As to why the original resistor blew.. That's its job. If the motor binds up, it produces a high stall current, and the resistor blows and protects the motor driver circuitry. The motor stalled when all that spaghetti and spring mallarky let loose.

cool deck

It's a quasi-clon of the Pioneer CT-3000 mid-component with changes....

Thanks! The eject mechanism is working fully; it’s not like a CD player where the eject button will pull the drawer in. The button here is fully mechanical, it simply releases a catch and the drawer gets shot out via springs. It is surprising though since i don’t think it would’ve have taken much to just add a switch to that button that activates the motor and pulls the entire drawer in.
