I will do another tube test of 300b's before shipping. Also includes 2 strong testing Western Electric 2C51 driver/input tubes. Amp is playing fine with the included tubes but will weaken over time of course. One tube is at minimum value GM and I suggest new owner buy a new pair of their choice. Anytime you are using a 2a3/45 or 300b amp it is a triode amp regardless of topology. The Bottlehead amp will probably be parafeed and will have SS rectification which some like, some dont, it will sound darn good though. The included 2 EH 300b tubes were tested on my Hickok 752A. Building an amp is a lot easier than a phono stage or other projects, especially if it is a kit. Buyer to pay for shipping and I will cover PP. Pickup in northern Cali is certainly an option. Does not come with a power cord which is how I received it.

I will use my Fedex account to give interested party an idea of ship cost. Shipping cost will be based on actual cost which will still not be inexpensive considering the state of things. Also, see the large spikes which screw into existing threaded inserts of which are now occupied with the substantial rubber feet which I added to the mix. See the pic of the base standing upright it can be noticed that the bottom is 2 pieces wedded together with large holes necessary to facilitate air flow. The amp came wired for 4ohm and I changed it over to drive 8 ohm speakers and will include the relevant pages of the build manual so that the new owner can change if desired.

I have all the packing the previous owner devised and I will improve upon that. The SET amp sounded great, but was point-to-point wired and the soldering and layout left a lot to be desired. The pack job on this is quite involved partially due to that the top plate does not screw down on the base. Two observations I found the build quality of the MP-301 (Mk2 and Mk3) to be noticeably superior to the MP-428 Mk2. I need to thin out my 2 systems in the house which is why I am selling the BH 300b. This Kaiju was built by BH tech and can be easily verified as I can give you his addy should you want to do that. For sale is my Kaiju 300b SET amp with DC filament upgrade enabling sweet 300b sound with no audible background hiss or other distracting business using my Tekton Lore reference 97db sensitivity.
