The Blue Circle BC3 PLS is a dual mono tube linestage preamplifier. It is also fully upgradeable all the way to the BC3000GZpz.
This BC3 PLS has all the same features functions and options as the rest of the BC3 lineup.
I bought this fine pre-amp from an AudiogoN member 3 years ago and it has had infrequent use, as I am doing mostly home theater, and thus the sale.
It currently has as options, the dual Shallco's with remote volume, blue chassis, and home theatre bypass. It has 2 sets of main outputs for home theatre, or sub woofer use.
It has been in my system for 3 years along with my matching BC 202 Amplifier, also for sale here on AudiogoN. I am open to a combined offer. No visible scratches or issues. I have recently reduced the price. In my 30 years in high end audio, I feel this equipment is very pure sounding and better than many pre-amps I have owned in the past.
I will include a spare unused 6922 tube and include shipping to US buyers on the pre-amp only. PayPal is extra.
I can't go into all the details about the BC3, but perhaps a description of the volume controls will illustrate the attention to detail that goes into its crafting. Each channel has its own volume control, totally hand-assembled from matched pairs of precision metal-film resistors, forming a true mono-ladder attentuator. Each of the 31 unique position contacts is constructed from military-grade coin silver and is self-cleaning. Each control takes approximately four hours to assemble. This is not a production preamp.
* external transformer power supply
* upgradeable all the way up to the BC3000GZpz. (in 4 steps)
* optional additions are USB input, phono stage, headphone output, and balanced configuration
From the Manufacturer ;
In the ten years or so since its introduction the BC3 design has remained essentially unchanged. Our attitude is that if a product is designed properly it shouldn't require regular upgrades and tweaks. This attitude is supported by the fact that the BC3 is still extremely popular and well regarded by the audiophile community.
The BC3 preamplifiers epitomize what Blue Circle Audio is all about. They typify how we believe components should be designed and crafted. They are not the most expensive components we make, nor are they the least expensive. They are the "meat-and-potatoes" components for that special someone who is deadly serious about music reproduction and doesn't have a totally unlimited budget. No bells and whistles, no remote controls (OK...we've become a bit more flexible on this one), no exotic cosmetic treatments and no submission to some fad or design dogma. Every penny you spend on these components is dedicated to music and simple elegance.
Preamps build around vacuum tubes simply sound better. There are good sounding solid-state preamps, and there are bad sounding tube preamps. But given the choice, when cost is not an overriding issue, tubes are the way to go. Here are some of the things that make the BC3 (MKII) worthy of your attention:
Still.. Dual Triode Single-ended Class A Topology
Still.. Totally dual mono in the signal path including volume and input selector controls
Still.. Totally handcrafted featuring point to point hardwiring and no PCB's in the signal path
Still.. Extremely high gain and current capability for long interconnect runs
Still.. only 5 resistors per channel
Still.. hand-built one at a time, run and tested for 50 hours and personally inspected by Gilbert before shipping
Upgrade to the Mark II
200% greater capacitance than the original in onboard power supply
dual HexFred rectifiers
all new internal wiring
Rubber feet....yes rubber!
silicone bubble mount tube sockets...trickle down tech from the AG3000
ultra high speed power supply caps used in the on board power supply
double the capacitance on output coupling caps for improved bass
low profile main chassis with indicator dots on faceplate for volume controls....no more counting clicks
volume control high/low level switch - with the high low volume switch there are a total of 62 volume settings available
improved wiring layout for lower noise
1% metal film resistor used throughout
DC power cord made in house by Blue Circle
Blue or black covers for preamp instead of stainless available upon request (power supply remain stainless only..or in the case of the Despina black only)
When matched with the BCG3 MKII the integrated preamp is called the BC3 DESPINA MKII. The BCG3 MKII comes in a simple black metal case with an integrated dc cord that mates with the BC3 MKII. It features:
High current toroid transformer
High speed recovery diodes
Double Reverse Twisted dc cord for RF noise suppression
...B+ rectifiers mounted in silicone for vibration control
The BCG3.1 MKII Power Supply
BCG3.1 MKII Power Supply
When matched with the BCG3.1 MKII the integrated preamp is called the BC3 GALATEA MKII. The BCG3.1 MKII comes in a beautiful stainless steel case that matches the BC3. It has a detachable dc cord custom manufactured by Blue Circle. The BCG3.1 MKII features:
Dual toroid transformers for greater current capability
Hexfed Ultrafast Soft Recovery rectifier diodes
200% more ac filtering and 300% more filament filtering
Integrated Power Line Pillow ac powerline conditioner
Mark II... B+ rectifiers mounted in silicone for vibration control
... Seperate B+ power transformer and rectifier
... DC and AC filtering 200% greater than original BCG3.1
... Filament filtering is 2.5 times greater than original BCG3.1
