Used Townshend Seismic Sink Mark1 (model number 1-01899) equipment platform. Size is 430mm x 360mm. .
Has done fantastic service under my previous Naim CDS1 CD Player. The new CD player has now moved to an equipment table, so this Seismic Sink is no longer required. It's in excellent condition, with no obvious marks or scratches (just faint marks from equipment feet).
The pump wasn't supplied - but any normal bicycle pump will do. The bladder shows no sign of leaks, but I found it beneficial to check it every 4 months or so. Has happily taken a 30kg power amp in the past. Weight is about 8kg, hence the high postage costs (could be picked up if you are local).
Happy bidding!
