does anyone have Osborn speakers?
Yes, I have Monument reference speakers. 
Cambridge 640P Power Supply Upgrade
I am using a 12VAC 10A transformer (from my junk box) in lieu of the 640P wall wart. It sounds better. I am also generating a nice clean 240VAC signal to power the transformer and my preamp by using a pure sine wave inverter running off a 12V 100A...

Yes, the first thing I did was to remove the solder blob. Anyway, the Prestige is long gone now and the La Fontaine rules the roost. It is a brilliant player.

I now see from your photos that my 845S amps are only similar to the 211 types internally. My resistors look as if they might be an upgraded type from the previous model 211/845 amp. As for the Psvane 845 'Hi Fi' grade tubes I am using, I read tha...

Regarding my 845S mono blocks, I have now replaced the original Shuguang 845B tubes with Psvane (Pavane) "Hi Fi Series" 845 tubes. These sound far better (to my ears) than the original 845B tubes ever did. Apparently their "Collection Series" tube... 
Best 845 tube out there?
Thanks for that. I suppose my experience was much the same but they are off again as I purchased a matched pair of Psvane Hi-Fi series 845's for my monoblocks. These have done about 50 hours now and are excellent tubes. Bottom end is tighter and h... 
845 recommendations from actual experience
My Opera 845S monoblocks came with 845B tubes which I always thought sounded very good not having any other reference. After they had done about 2000hrs and still sounding much the same, I swapped them for a pair of matched Psvane 845 Hi-Fi series... 
Best 845 tube out there?
Has anyone used Pearl Tube Coolers on their 845's? I am using them to hopefully extend their life and possibly reduce the small amount of microphonics. At first I thought the coolers dampened the HF end a bit but after trying the 845B's with and w...

Thanks for the great response to my post on the 845S monoblocks. As for NED KELLY, where have you been? He is only our most famous bushranger hero downunder in Australia (I am in Melbourne), GOOGLE him. I don't think I will get further into these ...

You are as game as Ned Kelly! I haven't gone any further than my previous post as I was so impressed by the improvement that I didn't think it could get any better. I thought about placing the RCA sockets on the side of the amps near the front but...

My source is an AA La Fontaine, amplifiers are Opera 845S monoblocks (DIY tweaked) and Osborn Reference Monuments. Interconnects are Osborn Silverlinks and speaker cabling is Neotech UPOCC. Lots of DIY room treatment. Main hobby these days is list...

Hello everyone. How is this club going. Are there any formal or informal activities? I would like to meet some like minded individuals. I like DIY audio but at present have mainly commercial equipment. David, Rowville, 3178.

I have the Opera 845S monoblocks. I replaced the Audience AuriCap coupling caps (2 x 0.1 and 2 x 0.47uf) with Jensen Copper PIO caps. I got a very significant improvement. In the last few days I have replaced the RCA input sockets with CMC silver ... 
Audio Aero Prestige new trans cannot read cd/sac
I purchased a new laser assembly, KHM 310AAA W/M and installed it. Nothing worked. After some poking around there was some activity (can't remember exactly) but no music. I put the old one back in and still nothing worked. After turning it on and ...
