1/26/2024 0 Comments Bias amp 2 settings for metalI tried other combinations, but kept coming back to how Zach shipped the Bokeh in the box. I think Zach read my mind or knows what I like because the Bokeh was set up exactly to my preferences with the protein pads and bokeh mesh. Zach sent a bunch of sundry accessories to let me tweak the Bokeh to my liking: two meshes, the Bokeh Burst Mesh and Solid-Mesh and three sets of pads, Protein, Suede, and Hybrid. (I hope you guys know I am being sarcastic because most of the type of amps only output 1-2W at most into 32-ohms). No need for the "most powerful" transformer coupled single-ended triode amps capable of driving the most current hungry planars. We are taking Grado or ETA sensitivity here. I believe normal impedance is 80-ohms (I will measure later) and it barely takes a turn of the volume to get Bokeh to high volumes. Not only that, the Bokeh is easy to drive. This time around, Zach heard the pleas of the working class: can't we have ZMFs too! It's my understanding that the Bokeh will be priced affordably. Zach is at it again, this time with the latest TOTL $5500 wonder! Just kidding. Here's the unpainted transformers on the 222c/d They looked similar, but a little worse, to the condition of the transformers on the 222c, which I failed repaint and will do later. I forgot to take before pictures, but the first order of business was to clean off the dust/grime and remove the output transformers and power transformer bell cap for a repaint. Anyway I'm starting to restore/mod the LK-48 and will keep a log here. It's the same circuit as the 222c, but again with a different face plate, and uses 7199 tubes for the phase inverter instead of the 6UB tubes in the 222c/d I restored already, although some 222c's did use the 7199. Then I came across a cheap Scott LK-48 for sale locally and grabbed it. I've come to accept that I just like vintage stuff and I like tubes and I'm ok with that. It turned out great and unseated my Ragnarok 2, not on technicalities, but on musical enjoyment. Along the way I decided to add the biasing circuit from the 299b. I recently finished restoring an early model HH Scott 222d integrated amp, which is actually the circuit from the 222c, just with a different face plate. (I mean GM doesn't sell a Vette with a V4 at $50k but ask an extra $30k for the V8.) If it sounds like this kind of audiophile bullshittery bugs the F outta me, it's because it does. For Jeebs sake, f'ing sell the best product that you can instead of something gimped that requires an extra attachment that makes it how it was supposed to be in the first place. Ferrum Audio should just sell both together instead of offer an "optional" power supply that makes the base headamp guuder. I have not heard the OOR without it and I won't because I don't have the time. The HYPSOS is a power supply does guud things. I'm going to be direct and succinct without much extraneous bullshit and technobabble (some it probably wrong or misleading) that other Internet reviewers spew. Due to the very recent release of a number of headamps which have really pushed what solid-state headamps can do (tube expressiveness), the Ferrum OOR is going to have some stiff competition. This is an honest review* of the Ferrum ORR headamp and HYPNOS power supply.
