For Sale: Croft Micro 25 RSLS with Khozmo passive attenuators and remote control

[pankon]

I have been a devoted user of Croft gear since 1989, when I was studying in the UK. I own six (6) Croft boxes.

The preamp on offer is the top of the Croft line. It is the Micro 25 RSLS with external power supply (230V) and dual-mono architecture, i.e. has two 12BH7A valves, one per channel. Glenn Croft has further upgraded the Micro 25 RSLS with Mundorf Mcap Supreme capacitors, better resistors and better RCA posts. The preamps has four (4) line inputs and two (2) outputs, so that even a subwoofer can be driven. No phono stage is included.

Croft owners know that if there is one point with Croft gear that has room for improvement that would be the volume pots (actually there are two of them with Croft amps). In this particular model, the inexpensive Tocos volume pots have been replaced by the excellent (and rather expensive) Khozmo shunt passive attenuators (discrete 64 steps), which were expertly fitted by Arek Kalas himself, the designer and manufacturer of Khozmo. Those attenuators come with two LED displays (one per channel), that indicate the volume level. Furthermore, Arek installed an upgraded input selector. A new, metal front-plate was cut with to accommodate the volume indicators. The workmanship is so good as if it had been designed like that from the very beginning.

And a very nice surprise is that the preamp now has a remote control. It’s a heavy-duty metallic remote control (not made out of flimsy plastic), that allows to control the volume of each channel independently or change the volume of both channels at the same time, change the channel and mute/unmute. All of that from your listening position, a very rare treat for Croft owners.

So, what about the sound? It is definitely cleaner, with more detail, less grainy and even smoother than the already excellent stock Micro 25 RSLS. The upgrade to the stepped attenuators was well worth the cost and the long wait, until all the mods could take place.

This is a one-of-a-kind Croft model, most probably the ONLY ONE IN THE WORLD. It is in full working order.

The preamp currently lives in Greece and can be shipped to anywhere within the European Union (to avoid customs controls and opening of the boxes). Shipping cost will be assumed by the seller (via EMS). The amps will travel under the risk of the buyer. Any additional insurance may be assumed by the buyer.The asking price is 2,400 GBP (incl. shipping costs). The preamp can be shipped within one (1) day after reception of the payment into seller’s bank account.

I will be happy to reply to any AoS members, if someone is seriously interested and needs more information. Thank you in advance.

Best regards,
Panos

P.S. I am selling this beloved Croft preamp along with other hi-fi gear (to be posted later), because I have decided to downsize my hi-fi systems.

Hi Geoff,

I am aware of the rules, but I am trying to figure out how to do it. I am posting at full size and the photos are automatically shrunk -((.

Thanks,

Hi Panos,

Got your PM, but thought I'd reply here. You need to use an image-hosting site, with which to upload your pictures, rather than going direct through our site.

Try this image-hosting site: https://postimages.org/

It's free and very easy to use. When you generate the link and post it on the forum, images will appear as full size:)

Marco.

[pankon]

Thanks, Marco. Very kind of you to respond so quickly. Please give me a few minutes and I will update the post (please do not delete it).

Best regards,
Panos

[Marco]

No problem. If you need any further help, let me know:)

Marco.

I've done it for you Panos.

Hey Panos,

That's a fancy box! I have an RSLS custom build also, not quite as flash as that tho. Did I sell you those KB/AD's?
I've put mine up for sale a couple times and chickened out; you have to keep a steady nerve :)

atb,
Mat

Mat,

you are the Mullard Man, aren't you? So, who could I have purchased those great Mullards from? LOL!!! And I have also purchased many other valves from you as well. It was quite a few years ago though.

Thanks for your wishes. I have decided to scale down my system, although I've gone to extremes to get especially this Croft preamp to the point it is right now.

Cheers,
Panos

That looks like lovely installation and neatly solves the croft bugbear of "are the two volume pots set identically?!"

Quite right so, Graham. Having a remote that can control both channels simultaneously or one channel at a time is something that Croft owners can hardly imagine. But in my opinion, it's the sound quality of the Khozmo dual-mono passive attenuators (shunt with Z-foil resistors) that really make the difference... -))

[anubisgrau]

geia sou panos, any idea how much amplification (or gain FWIW) this preamp provides?

Hello (geia sou) Gordan,

no, unfortunately I do not have the information you are requesting. Unless I am mistaken, Glenn (Croft) does not publish such figures.

Cheers,
Panos
