Description.
Designed primarily for field and studio work, the half-track Uher 4000 Report was originally released in 1961. Many variants appeared over the next few years (the 4000 L in 1965 pictured left), the 4200 stereo and the Report IC (integrated Circuit) 4200 and 4400 stereo series which were available into the 1980’s. With four playing speeds (15/16 ips to 7½ ips), this battery-operated recorder was capable of a frequency response of up to 20kHz. The sophisticated motor control system used no less than 8 transistors, 3 diodes and a voltage reference zener diode.

uher: UHER report 4000-S
I have an UHER report 4000 -S in very good condition, except that the motor runs a few percent too fast when I test the recoder with my test tape. I have found a lot of information on the report 4000-S model, but no information on how to adjust the motor speed. It runs about 1,5% too fast.
I would be very greatful for any information or hint.

Long live magnetic medium.
I have one I picked up at a thrift store a few years back,came with the leather case and an accessory case,need to get some info on it and figure out what it would take to get it up and running.Seems like it is built like a tank,I'm sure it's worth investing some time in. Rob

I had one years ago. I had bought or made DIN connector adapters to play it through my stereo. It was a good sounding machine.

Serious tapehead.
These are wonderful little machines!! I have 3 of them, a 4000-S, a 4000-L and a 4000 report monitor (which is at work with me right now as I type this). They are pretty simple to work on, belts are still available on-line, many accessories can be found on Ebay as well. They were made for over 30 years (the last year for them was 2002) and I think I read somewhere that during their history, Uher sold more than 800,000 of them worldwide, mostly to governments, and the news reporting industry. The 4000-L I have came in its leather case that has stickers on it from the US secret service, one can only guess the conversations that machine recorded! Its worth restoring, especially is yours is still working. The "S" series was all germanium transistor and can suffer from the numerous "Frako" capacitors that go bad over time causing weak sound and speed consistency issues. Give her a good clean, replace the belts and see how it goes, if everything else seems good, leave the electronics alone for now. If something starts to go awry with the electronics, it will be very evident. To see two of the machines I have, go to the Y-Tube link below. http://www.youtube.com/watch?v=aCHFlxDZfAk Good Luck *reelspin* P.S. - the lid on this is not plastic, the case is all metal!! Very heavy and very effective as a weapon!!

By the way, you can use a lead-acid (UPS) 6V 3.3Ah battery in place of the 5 D batteries, it fits perfectly in the place of the Uher rechargeable battery and provides a lot of play time. I use a 4400 IC to record lectures at the university (2.4cm/s with a 550m reel - 6 hours per track).

Pentium100 said: Some guys on ebay (.de) are selling those batteries (at a higher price than what I can get locally) and say that they are compatible with the Uher. So I went out and bought a battery. You need to bend the terminals (of the battery) a little, but otherwise it fits OK. It also lasts a long time, at least on my tape recorder - I once used it almost the entire day (recording a few lectures then playing music using its internal amp and external speakers) and the battery still had charge.

The guys who made some of the first rock bootlegs (dub and ken of TMOQ) used one of these with a Seinheiser shotgun mike (painted black to avoid being spotted by security). They recorded several Rolling Stones shows in 1969, one of which from the Oakland Coliseum became the famous bootleg "Liver Than You'll Ever Be". The following year they also recorded Led Zeppelin at the LA forum and released it as "Live On Blueberry Hill".
