Richard is correct.
But I think the original listening station was in Hut 1, in 1939/40. B Block was built after the intercept station had moved off site.
The diversity racks of AR88's are a reconstruction of the intercept station at Knockholt, which monitored Lorenz-encrypted teleprinter traffic and provided raw material for the Tunny and Colossus machines.
The Computer Museum is open on Thursday, Saturday, and Sunday afternoons plus some other days as publicised on their website - the reason it can't keep the same opening hours as the adjacent Bletchley Park Museum is due to the limitations of being staffed by volunteers and funded by donations.
