Hi Noel thanks for the reply. Picture sync is terrible so I'm led to belive that it the notorious electrolytics on the servo board.

Cheers, Ian

Ian,

I can take photos of some pages if you send me your email address and tell me what you are specifically interested in. What faults are you trying to fix?

Hello to all, Ive been trying to locate a service manual for a SL-C5UB for some time now but no luck, anybody on here have a spare or copy to help me on my quest to repair my machine.

Thanks, Ian

Hi Noel,

With the HF950 fast capstan issue - I have the exact same issue with a HF100. Started off as an intermittent fault but has progressively become worse, so much so that's now constant. I'm working through the circuitry and have a donor machine so have swapped components and boards narrowing it down to the main servo circuitry (not capstan motor or drive PCB). I'll post the fix when I find it in the the hope it helps you...

Many thanks,

Alex

Hi,

I'm trying to get an AG-7 tape changer working with a C7. I have a later machine with the C7 logo on the front flap but I'm starting to suspect that the machine itself is of an earlier version which doesn't support the AG-7. I searched a while back and found info on the modification but for the life of me I can't find it now. Does anyone have the details for the modification at all? Would be so great to get this up and running finally...

Many thanks,

Alex

Hi James,

As Noel suggested, the C80 was sold in Australia under the -AS suffix.

In Spain we had the C80E version, which was very common. Today, it is not difficult to spot one in an assorted degree of conditions. It wasn't sold in many different countries AFAIK.

It is an overall simple machine, despite its appearance. Its mechanism is mostly based on the C30 model with an improved three heads assembly for perfect pause and frame advance. Because of that, it makes use of a dedicated additional board.

From the ones I have serviced, I can say many of them suffer from common issues (black loading gear, 3H Hall sensor and its dreaded glue, planetary assembly and eject left gear among others). But they also develop poor loading and threading torque, muffled audio and display issues. The clock/counter one is usually quite faded. The secondary (timer) is usually bright but you can only enable it vía the original remote: the huge RMT-220.

Right now I own a very special specimen in grey color. And the remote is also grey!

Greetings,

Gabriel

James,

The Sony SLC80AS was the model sold in Australia and there are a few around but they are not that common. They were marketed as "sports" model with two timers and the most strangely designed remote control of any Sony beta.

You get a real time tape readout and perfect stills. (care of SLC9 heads)

Most of the ones I have seen have issues with the timer displays failing. I have never spent much time trying to fix that.

Hi James,

Un which country are you based? Depending on that, the C80 can be relatively common.

Thank you Noel. I did not know of that site. I have a manual for my SL-C30 now, thanks. I have found the fault - one of the plastic gears in the cassette loading assembly has lost 2 teeth because an axle used in the loading sequence was too tight for the teeth. (It's hard getting a cassette out of the machine when it is already lowered.) I only have 16 tapes I have to convert to digital so if I can't find a gear I will have to load and unload each cassette by hand. I think it plays OK but I have not got that far yet. Thanks again.

Dear Noel,

Have you checked you have the 4'43MHz signal in the servo board and main servo IC? This is usually generated within the video board so you can track it back.

Gabriel

Roger Bailey,

The SLC30 has two actions when its loading and unloading. Dropping the tape into place while flipping up the cover flap - then threading the tape around the video head drum assembly. The second action is controlled by a small black gear that can break which affects the driving of the load ring which wraps tape around the head.

Your problem however sound like a broken gear inside the large clear/white disk gear on top of the load motor. The gear driving the planetary gear set that mounts over the motor shaft (and has a D shaped hole in it) often cracks and jams. They are under a lot of strain so it is unlikely you can repair it, you just need to get a replacement if you can. Also make sure that the swiveling end underneath the lever that is driven by the capstan roller solenoid has not accidently been placed the wrong side of the metal pin that sticks up. This lever controls the change between loading and unloading action from cassette in and down to the tape being spooled out of the cassette and visa versa when unloading.

regards Noel

Hello all,

I am wondering if anyone knows the cause of a fault I have on two SLHF950 machines.

I repaired the faulty slides on both of them. Now I try a tape in play mode and the capstan runs full speed tangling and damaging the tape. I can get the machine to pick up most of the slack if a hit rewind but that only work momentarily before it stops. The drum motor hardly spins at all. The three electronic fuses are OK - not blown.

I suspect there is a fault on the SS50 board. Voltages in measure correct. Any ideas?

regards Noel

The only Audio I get is from a tape that has Hi-Fi from all outputs including the RF and the level meters are working.

There is no audio from the built-in Tuner or any tape that only has mono/analog sound and the level meters show nothing.

Audio inputs appear to be working.

I am just not sure which board I should be looking at yet.

JamesF - Do you get any audio from the headphone, or rear phono or scart outputs, and does the levels display show any activity?

I hope this helps you Roger Bailey I think a small gear that loads the tape might be cracked.

Thanks Mark, I am sure it is not that as there is no normal audio on the tuner, which it did have before.... before it stopped working there was crackle pops sounds. Which makes me think a transistor has failed or maybe a capacitor?. Will give it another clean and see if anything changes.

James
