Preamp Deal of the Century

If anyone is looking for a true "World Class" preamp at a very fair price..heed my advice. I just recieved a Supratek Syrah preamp that was hand built by Mick Maloney in Western Australia, and it is absolutely beautiful! This preamp is the best deal you will ever find. I would put it up against any preamp out there for both looks and sound. Price? $2500 for the Syrah (includes Killer Phono stage). Not into phono? Try the Chardonney line stage for $2100. Don't get me wrong, I am not associated with this company. I am just a very happy owner! This preamp is VERY dynamic, yet liquid. It conveys the sound of music better than any other preamp that I have ever heard! You can check out the Supratek website at www. cantech.net.au

Ethifi,

In my experienced, the problem you described should come from the Bendix 6101. I had the Bendix beforehand when I received my preamp and found out the same anomaly as you pointed out. As you increased the gain, the popping (like a motorcycle idling) and tube rush sound increases in proportionality.

The Syrah can use the Bendix, but the Chenin (as Mick told me long ago) cannot due to a small change in the PSU. Maybe the new Chardonnay incorporate this change also.

goodluck

When I wrote about the problem, the stock regulators were already back in place and there was no noise, even at maximum gain. Current setup (no noise): NOS rectifier, stock regulators, NOS 6SN7.
I also experienced no noise with this config: NOS rectifier, stock regulators, stock 6SN7. I have tried all combinations. Conclusion: as long as the NOS 6F6G are used, there was popping noise.

Ethifi, I was using a Syrah before and now I am having a Chenin. I found no problem with Bendix, GZ32 and GZ34 with Syrah but for the Chenin, only GZ34 can be used. I was probably the first or second guy to own a Chenin and the first guy to realise this noise problem. I even shipped the whole unit back to Mick for inspection. I am using Sylvania 6F6G but there is no such problem found. I would suggest you to try out a pair of Sylvania 6F6G and see how it goes.

Ethifi - Sounds to me like you need some new 6F6G's. I'm not sure what the "Brima" brand is... Did you mean Brimar?

Tubeworld has a good selection of NOS 6F6G's. They may cost a bit more than you'd pay on Ebay but you'll be taken care of should you have problems with a particular tube.

Tubeworlds tube list is at:

Also.. what is this 3 way gain switch you're talking about?
I've only seen low/high gain switches on Chardonnay's. Is this a new "feature"?

Hi Bwhite

Yes, these are the Brimar (typo mistake) and they are NOS from TubeDepot (perfectly matching pair @3080 uMHOS according to TubeDepot). My Chardonnay has low/high gain switches on the top panel and 6-position switch at the rear panel. The rear switch varies the load on the output transformer. I use the high-gain position on the top panel switch and the 3rd position on the transformer load selector. I am not sure whether the rear switch is a new feature. I have written to Mick and am waiting for his reply.
