BLK 45

The BLOCKHEAD BLK 45 is an exact replica of a 1965 Marshall™ Block Logo JTM 45 amp. An absolute tone machine, with it's custom wound output transformer, heavy duty replica power transformer, Sino KT66 output tubes, Sino GZ34/5AR4 rectifier and JJ/Tesla ECC83 preamp tubes, and tweaked 5F6-A circuit.
There truly is no other amp available like this at any price, anywhere. Just one look inside, and you will see exactly where every dollar went in our development, and your purchase. Most, if not all, of the "boutique" amplifier makers use the same 25 cent parts and modern transformers that the mass produced amp manufactureres use. However, putting expensive "HiFi" type parts in your doesn't make much sense to us either. The key to our parts is finding the right component for the job. SO, HOW DOES IT SOUND? Just like the original! $2,275.00

This is a JTM replica with a little twist. It is a stock 1967 JTM circuit, 5ar4 tube recto, 2- el34, 3 ecc83. The transformers are authentic. The power transformer is a low voltage model running 300 volts- this leads to a softer, sweeter breakup with a little less headroom than the higher voltage transformers found in the later 50 watters.  The output transformer is el34 version of the radiospares transformer, it has a primary of 3.4k with m6 laminations. we think you will find that this OT retains the clarity and sweetness of the Splitfront OT, but runs lower impedance to accommodate the el34.  Another special feature is this amp ahs a split cathode.  Channel 1 has a .68uf/1K bypass to accentuate the mid response, channel 2 has a 250uf/820ohm bypass which is a stock setup, giving the classic big bottom of the early marshalls

The white one that is shown is a prototype and is not for sale we have black ones in stock a white one can be ordered but that would be backordered for several weeks.  $2,275.00
