Berlin record stores

Want to know 'cause I'm spending a lot of time in Berlin (e.g. this weekend for Matmos, perhaps moving there for a while in August) lately and the U2 goes everywhere I want to go. Oh well, better than when the U1 was closed and I lost convenient transportation to three of my favourite fast-food joints. Sorry for the thread derailment.

There's always a replacement bus service, it's a bit slower but being Deutsch über Reliable.

no pun intended, presumably.

Spacehall mentioned by Tuomas above now has 2 shops next to each other on Zossener Strasse -- one vinyl, one CD. Both very large, new and secondhand. Perhaps worth a visit if you are in Kreuzberg 61.

Off there on Thursday for the first time... Any further tips?

rumpsti pumpsti is tucked away down a side street in neukölln & is awesome for soundscape concrete aktionist rumble & drone & abstract laptop music / sound-art http://www.rumpsti-pumsti.com/ Weserstrasse 165 & not so far away from the staalplaat store (Flughafenstr - a 10 minute walk) which reminds me of howard & andy jacques' these records in elephant & castle when that was going - tons of stuff - jap avant prog, field recordings, drone, noise, etc. spacehall in zossener strasse does indeed have a smashing techno vinyl ( vinyl building a couple of doors down from the cd shop, nice tibetan eatery over the road from it ) - you really had better know how the techno you're looking for is categorised tho cos it's all filed by category - is it "retro deep tuesday step" or "dark balaeric nu-afternoon beats" - you can always ask the ladenbesitzer ( or ladensitzer as i like to call'em ). managed to pick up a couple of morphine records 12"s & an oni ayhun - whoop!.
never got around to visiting Dense records cos i bust the chain on the bike i borrowed. musikdrehscheibe / musik unter den gleisen: Friedrichstrasse 128 has a rummaging basement but I didn't really see anything of interest - i'm sure that stuff comes & stuff goes there. i'd suggest skipping it if you're on a tight schedule. The Mauerpark Flohmarkt (Sundays) isn't really much of a "flea" market, just stalls and stalls and stalls of guys selling damp old ryuichi sakamoto lps for 30€ a pop - who knows you might get lucky with something but it will take you forever to trawl the whole market ! i got nothing but i enjoyed the stöbern ! there is a good variety there i did see both bogshed & material lps, which makes a change from peter maffay & udo lindenberg, i guess!

Amazing, thanks!

2nd hand electronic stuff?

One of my favourite record shops closed last year and is now this bar: http://www.hackendahl-berlin.de

It's actually a cool bar, but still... *sniff*

Mr.Dead & Mrs.Free near the Nollendorfplatz closed in February. I haven't checked the successor, riseikel yet.
