**** Summer Sale Update ****

 Hi!

Half of the equipment from the previous summer sale post is sold, so I am writing an update and also offering some price reduction or better deal on the remaining items

I can ship world wide. If you are interested in a unit please ask for a shipping quote to your country. I have plenty experience in international shipping and pack very safe. However please note that import duties might apply if you are outside the EU. But therefore every sale outside the EU is VAT free. Personal pick up is possible too of course

Each unit will be equipped with new tubes, tested and matched. Each unit will have warranty backed up by me.

This is your chance to grab one of these at a bargain price!

Here are the remaining pieces on sale:

A pair of Compactron mono power amplifiers

A solid 15W per channel, 8 Ohm. Parallel Single Ended.

Condition is a bit funky, the black top lid is quite sensitive and has some blotches.

More info about these in this blog post.

Therefore only 11.000,- the pair (9.240,- export). I cannot go lower on the price for these due to the material cost. Except for personal pick up, some discount is possible.

Next something truly special, the first version of the Intrepid line preamplifier.

All silver differential design with Elrog ER801A directly heated triodes,

Silver output transformers, silver plate chokes, silver input transformers (16 silver pieces total)

4 XLR inputs each set for different gain. More details here.

Reduced Sale price 49.000,- Euros (export 41.175). This is the lowest I can go on the unit. The price is approaching the raw material cost (16 silver wound transformers and coils! chassis milled from solid metal)

Next a 3 chassis DAC with DHT transformer coupled output. Silver transformers!

Used as demo unit only. Some signs of wear.

Coax and USB input. RCA and XLR outputs. More details here.

Sale price 16.000,- Euros (export 13.445) 

Please note that the cost of the silver output transforms in this unit is already 7000 Euros. This is the last chance to get such a DAC at this pice as it will be dismantled for parts reuse if it doesn't sell.

And lastly I have some power amps to offer. The first is a set of single ended 845 mono blocks with 887 driver.

Each mono block has a separate power supply. So 4 chassis total.

The custom made Elrog ER887 is transformer coupled to the ER845 output tube. 25W per channel

Spare sets of ER887 and also ER845 can be purchased with the amp.

The power supply uses Elrog ER274A and 6AU4 rectifiers. Spare ER274A also available on request .

Good condition, but one of the wooden frame is slightly lighter in color. Barely noticeable. Used as demo units and for audio shows. More info here.

Sale price 35.000,- Euros (export 29.410). The price is for the set of 4 chassis including all tubes.

If you are able to pick these up personally and I do not have  to provide the wooden shipping crates I am able to offer a good discount.

If you are worried about the special driver tube type: The driver stage can be easily rewired to accept 211 as driver tubes.

That's all I have left as demo units. I am open to reasonable offers if you take more than one unit or if you can pick up personally and I don't have to ship. But of course I can ship world wide. Please understand no modifications at these prices. Email me if you have any questions. I guarantee that you will be happy with any purchase or I offer money back.

Best regards

Happy New Year!

Hi!

Another year is ending and times are changing.

You probably noticed a reduced number of posts on my blog during the recent months and exactly one year ago I posted the very last tube of the month article. Times are changing and blogs are not catching as much attention as they used to. I already started posting on Facebook in parallel many years ago and more often than on my blog. This year I also finally registered on Instagram and started posting there.

So this is probably my last blog post for a while. If you want to get updates about my work in electron tube electronics, follow me on Facebook and Instagram (see previous post for a link).

Wishing your families and yourself all the best for 2025

Demo Equipment Sale

*** UPDATE : Sold items are marked accordingly ***

*** Price reduction on some units ***

Hi!

During the last year I developed some new lines of electronics which resulted in a lot of demo and prototype units. These served mainly to launch the new products at the High End show in Munich. As last year I am offering some of my demo units at a bargain price to make room.

Here we have 5 Compactron units and the prototype Intrepid linestage. These have only been used by me in my workshop or at the Munich High End. All units are in excellent condition with occasional minor marks. Detailed photos are available in case of interest. Each unit is functionally 100% working, tested and comes with warranty.

Of course each unit is equipped with tubes and accessories will be included as with a new unit. The feet are exchangeable and can be chosen between pointy, straight sided or tapered. Besides that no changes possible.

I can ship worldwide. The exact shipping cost will be quoted in case of interest. Personal pick up with previous listen test can be arranged too. In case of pick up I can offer some discount.

And most importantly: Money back guarantee. I will accept returns within 2 weeks of receipt of the units and reimburse the payment, less the shipping cost. 

The regular sale prices and specs can be found on my product site.

This is a Compactron Integrated Amplifier. Click here for a detailed description of this unit.

*** SOLD ***

This is a Compactron DA-Converter Click here for a detailed description of this unit.

Not available any more. I decided to keep it as demo unit since it is the only single chassis DAC I have in the moment.

Transformer volume control Compactron Linestage Click here for a detailed description of this unit.

*** SOLD ***

This is a Compactron phono stage  Click here for a detailed description of this unit.

*** SOLD ***

Next we have something truly special, the prototype of the Intrepid line stage, in this case still named 10Y Line Preamplifier. This comes with all the goodies of the Intrepid series, all silver transformers, chassis milled from solid blocks, in this case with glass pearl blasted surface. Comes with a matched quad of Elrog ER801A tubes, but can be ordered for other tubes as well.

Click here for more details on this particular unit.

Sale price within the EU : 55.000,- Euro (incl. VAT) , export price outside EU without VAT : 46.200,-

This is an exceptional line stage capable to transform an entire system to another level. 

I also have two units in the classic chassis style:

First is the 6J5 line preamplifier which I already offered in last year's demo equipment sale . Last year I expected this to be sold the quickest, but surprisingly it was one of the few items unsold.

Details here. 

Sale price within the EU : 4500,- Euro (incl. VAT) , export price outside EU without VAT : 3780,-

This DAC was sold during last years sale, but due to some incompatibility issues with the buyer's media server I took it back. This unit is using silver output transformers.

Sale price within the EU : 17.500,- Euro (incl. VAT) , export price outside EU without VAT : 14.700,-

That's all I have on offer right now. Contact me for any questions or a shipping quote. I am open to reasonable offers if you are picking up personally or buying several units.

Best regards
