Upcoming amps, preamps and DACs with Compactron tubes

Hi!

A whole bunch of new stuff is in the making in my Compactron line of electronics.

After the introduction of the Compactron Preamplifier and getting orders for a Compactron line stage and Compactron phono stage I decided to launch a full line of electronics with Compactron tubes. The following gear is planned to be finished until end of January 2024:

1. Digital to Analog Converter with Volume Control

This DAC is based on the same concept as my previous DACs just with different output tubes and a more compact approach with simplified power supply so that everything fits into a single chassis. The output will be volume controllable using transformer volume control. This is for people who use digital sources only. It can accept data from a laptop/PC or music server via USB or from a transport via Coax. It can drive a power amp directly through long cables.

2. Preamplifier

A simpler version of the first Compactron Preamplifier. It has a phono section for MC cartridges, a balanced input and two SE inputs. A full function preamplifier but with minimal features, just volume control and source select. Volume control done with transformers. It will have both RCA and XLR outputs and low output impedance.

3. Stereo Power amplifier

A single ended power amp with 5W per channel, two stage design, interstage transformer coupled. Like all Compactron electronics in a single chassis.

4. Digital to Analog Converter

The same as the one above but without volume control. Meant to be used with a preamp. Transformer coupled output. Balanced and single ended outputs.

5. Phono Preamplifier

A entry level phono preamplifier for MC cartridges. Meant to be used with an active preamp.

6. Integrated Amplifier.

Single chassis integrated stereo amp based on the same circuit as the power amp above. 5W per channel.

7+8. Mono power amplifiers.

A pair of mono blocks based on the same principle as the stereo amp above but with 10W per channel.

9. Digital to Analog Converter

A simplifier version of the DAC listed as nr. 4. RC coupled outputs, RCA out only.

10. Line Preamplifier

Line preamplifier similar to the one which I built already. Just without phase switch but 2 balanced inputs and 2 SE inputs.

I plan to demo all these at the Munich High End 2024. Yes I plan to be there again. Each of these units can be customised with different features. Chassis will be made in different colors to showcase the possibilities. Stay tuned for updates as assemblies of these units starts.

Best regards
