Universum System 8000 amplifier - first look!

This is a BEAST!

[@bluenazz]

Really nice score J! It will be interesting to see how it sounds after you give it some love!

[@Maxxarcade]

@DrCassette Sometimes optional brackets are used for rack mounting.

[@chairuser4]

What a power beast it is,amazing quality.

[@FelixTheHouseFreak]

What exactly is the function of the muting switch?

[@mrgpcgpc]

I own the system 8000 tuner, amplifier and cassette deck. They are all in perfect condition, and they are some of the best gear that I own.

[@DrCassette]

@23chilled No, not on TV. You got a catalog and you ordered by sending a card back to them.

[@MrComputerfan]

The VU-Meters of my System 8000 only move a little bit on one place of the scale, do they need some oil?

[@vdochev]

@DrCassette Yeah, you're right, there are no screws. But the design is good. The heatsinks are in the back so you can put things on top and it is massive so I presume there are less vibrations. Maybe it is useful for a DJ. Anyway it looks like a great find! I would never throw such a nice piece in the garbage! How many watts does it pump out? You should make another video when you're done restoring it.

[@douro20]

@vdochev 300wpc into 4 ohms. From looking at it, it is probably a Darlington push-pull amplifier.

[@homersimpson6834]

Enigma 👍👍😍 das album habe ich auch unter anderem...

[@Noneatme]

Hey! Do you know how to change the VU Meter light bulbs? Mine are not working anymore. Thanks!

[@DrCassette]

I sold this amplifier 6 years ago, so I really don't remember how it was put together. Looking at this video, it seems the light bulbs are mounted behind the actual meters, so they should be relatively easy to get out once you remove the top cover.

[@Noneatme]

Thanks! Sadly, VU light bulbs are very hard to find nowadays... Any Ideas how I should proceed? Are there some universal light bulbs I can use or should I reverse search them with the information on it?

[@DrCassette]

Light Bulbs unfortunately are rather troublesome to replace. You need to know the operating voltage (which you can determine simply by measuring the voltage supplied to the bulb) and the operating current, which in case of a bad bulb is much more of a problem because often it is not printed on the bulb. If you could find the service manual for the amp the specifications of the light bulbs are listed in there. Oftentimes I don't bother replacing light bulbs, especially when they are hard to get at and specifications are unknown. In those cases I get creative and replace the bulbs with LEDs, but this usually requires modification of both the electronics and the chassis.

[@MrComputerfan]

I turn up the amp, but they only move closer to the + and only move maybe a couple mm back and forward.

[@MrComputerfan]

I got the same Amplifier, its very cool, I got my Record Player and my Cassette Deck connected to it.

[@DrCassette]

@douro20 Actually 100wpc. 300wpc is impossible as the maximum power consumption of the unit is only 350w.

[@DrCassette]

@GanEdenVideo I don't think so. They are rounded and have no provisions for screws. I think they were just decoration. That was common on early 80s equipment.

[@costellom5]

This seems to be a pretty nice amp.I would definetly clean it and recap it. :)

[@theultragamerx9169]

What songs are playing at 10:10 and 11:22

[@PileOfEmptyTapes]

@FelixTheHouseFreak Making things quieter temporarily, as shown. (So you can respond to whatever else may be demanding your attention.) It can be quite useful if you've got problems with channel tracking in the volume pot when playing back modern-day CDs and such, too. That amp definitely deserves some TLC, nice unit. Apparently it's from about '79.

[@EastAngliaUK]

Looks a good amp lucky find I guess was chucked out due to having them dim jacks maybe?

[@DrCassette]

@23chilled But was the Pioneer A91D sold by a home shopping company? I don't think so. This amplifier is good for what it is - comparing it to equipment made by companys such as Pioneer is just not fair.

[@DrCassette]

@vdochev These handles however can not be used in such a cabinet because they don't have any screw holes, plus I don't think that all has the right dimensions.

[@vdochev]

Professional equipment components have these handles because they are made to fit in large cabinets and connect to other systems. This is for easy and quick replacement.

[@PitifulHeartless]

anyone got a manual ?

[@yupimbackk]

Try picking up my Mcintosh MA7000 Integrated Amp,,,,,, It weighs 98 lbs. Love your vids...

[@myhay576]

alot of matsushita caps in there and is din-45500 nice one

[@MrComputerfan]

I cant oil them anyway, I already tryed to take it apart, but that was very hard... so I put it back together... I also found out the meters are sealed by a red label and I didnt want to break the switchs on the front. The Numbers on the Capacitors looked like it was made in 1978.

[@DrCassette]

Hmm, that doesn't sound quite right. Not sure what could be the problem though. However, don't mess around with the meters. They are very easy to damage.

[@SproutyPottedPlant]

That amp has some awesome fuck off caps!!!

[@DrCassette]

Give me the time code (for example 0:00 ), so that I can click it. I'm not going to watch the entire video to find that music part.

[@DrCassette]

Google for DIN to 3.5mm adaptor.

[@DrCassette]

@biggdaddy2001 As I already said, this is covered by the US "fair use" regulations, so I don't expect KZbin to cause me any trouble. I have seen other partners playing much longer music samples, without getting into trouble. You just have to stay within the limits.

[@DrCassette]

OMG no, oil is going to permanently damage them! They will move accoring to the output volume, not according to the input volume. If you turn up the amp, they should move around quite a bit. At low volumes they just won't do much.

[@janoschamann3008]

Machst du auch deutsche Videos?

[@DrCassette]

Technik-Videos mache ich nicht auf deutsch, aber alles mögliche andere, Reisen, lokale Ereignisse und dergleichen lade ich auf meinem Vistavox-Kanal auf deutsch hoch.

[@alexandrossotiropoulos5621]

Very nice amplifier. if the amp was mine, I would place a toroidal transformen and new power supply capacitors and after that this beauty would fly!

[@DrCassette]

No, no, unfortunately any kind of copyrighted music played for longer than 10 seconds is going to attract the copyright police.

[@dunstun365]

I think you can get away with playing copywighted music if its only being recorded with the camera mic. KZbin seem bothered only if music is piped in to the computer via a lead to the soundcard. That"s what I found out.
