re: D-RV7

I desperately need an English Copy of the instruction manual as I don't read German. Can someone send me a copy? I found the manual on this page.Thank you for the manual. I see that Radio Shack sold it as the Realistic SCT-42

re: D-RV7

Thanks for creating the new D-RV7 page and posting my manual so fast, always gives me a thrill to see any stuff I upload become available to the world.

Here's a pic of my deck, how could I get it on this page?

Seems my deck is rather a rare model, one of only a few Hitachi made with Autoreverse I believe. Another model being an D-X6, same as mine with a more modern look. And a deluxe D-X10 3-head auto-reverse, I always thought they were mutually exclusive, wow!

It's a great deck, had some fun repairing the auto-reverse mechanism a while ago. If anyone needs a belt routing diagram, or is wondering why their auto-reverse jams, let me know, I have a few ideas.

UPDATE: I just found out the Realistic SCT-42 deck is a carbon-copy of the D-RV7. I found a chap who had one with the owner's manual, and he very kindly scanned it and uploaded it to this site for me. Here's the page:

(Thanks earlcatmusic, been looking for one for years, you really made my day!!)

Cheers!

Dear Bellarmine,

I'd be keen to know where you got the replacement capstan belt from, mine has failed.

Many thanks, Karl

Hi Karl,

I don't know if you still need help with your D-RV7, just saw your comment now.

I haven't actually replaced my belt yet, but another fellow told me the "10.5 inch FBM flat belt" from StudioSoundElectronics works great. I've done business with them before, excellent company. Bought a new HiFi head for my old Panasonic VCR years ago, works perfect. The have parts for VCRs, tape decks 8-track, dial bulbs etc etc, all sorts of things.

They also have a very good how-to on measuring old belts:

Here's a place that has a belt specifically for the D-RV7:

Let me know if you want a pic of the capstan belt routing, as the two flywheels have to rotate in OPPOSITE directions for the auto-reverse to work properly. The belt wraps around the R flywheel but over on top of the left flywheel (not underneath).

Finally, if you need a user manual, I found out that one of Realistic's decks is simply a re-brand, and the manual for that has all the info you need. I have not been able to find the original Hitachi manual anywhere; one was supposed to have been included with my deck when I bought it (the seller lost it, groan!....:o). However simply search for Realistic SCT-42 here on HiFiEngine and you'll find an equivalent.

Hope this helps, any other questions let me know anytime Karl. Cheers!
