HI

 

I have had the following audio gear in storage for several years and have now brought it out to review usage or sell (wife very keen on second option :O) )

 

The gear is Cyrus II Amplifier with PSX power supply and a pair of Celestion SL12Si speakers

 

I have hooked everything up and it all works but doesn't seem to sound the same as when last used.

 

However as the only audio source I have is my phone via headphone jack I am not sure what might be the source of this problem.

 

Given everything is working what kinds of things might need to be refurbished/ replaced to compensate for the years of storage.

 

Thanks for any advice

This is exactly the problem. No mystery involved.

 

It would be best to find a decent source in whatever form you prefer. Streamer/dac/ turntable or CD. Keep an eye out for listings in the forum classifieds, but even with new gear it need not be costly for a quality source.

HI Rantan,

 

So you think the unused time in storage is unlikely to have had a damaging effect. That's good news. This was quite expensive gear when I bought it so its a shame to think it might have decayed

 

Thanks

 

Kevin

Welcome Kevin, I hope your gear comes back to it's former glory and gives lots of pleasure again.

I look forward to your posts.

Sometimes corrosion on the connectors can have an adverse affect on the sound.  Also the climate or the conditions under which the equipment was stored.  I always recommend full plastic wrap and back in the original packaging if possible, removing batteries from the remote controls and always in a cool dry location.

 

Electrolytic capacitors can deteriorate with age, but I'd investigate other reasons before doing a re-cap job on the amplifier or speakers.

 

To remove any corrosion from input or output sockets / jacks I recommend DeoxIT.  Works really well and a kit will last you for years.

https://www.jaycar.com.au/deoxit-contact-cleaner-rejuvenator-solution-kit/p/NS1436  I use it regularly on older gear that comes in for repair or restoration.  Inexpensive and cost effective solution to problems related to corrosion (within limits) or noisy contacts / switched etc.  I'm sure you will see similar recommendations from other experienced service persons on this forum.

 

Cheers,

Alan R.

Not familiar with the SL12'S but we sold a lot of SL6/Cyrus combo's back in the day and it was a synergistic combination.

I would not sell the system as it would, imho, cost a large amount to replace it with something better. The Cyrus amps take up so little space and so as others have said a decent source will brings the system bang up to date in the sound quality stakes.

Usually it is the speakers that seem to annoy women folk :)

There are a couple of good techs in Perth that could give the amp combo a once over regarding the electrolytic and checking bias etc and these day's I tend to recommend Mike at Liquid Audio having benefited from his advice on a number of my own projects.
