Hi all, up for sale is a Mjolnir Audio KGSSHV Mini amp for electrostatic headphones, your regular KGSSHV housed in a compact chassis. Drives everything Ive thrown at it wonderfully, rock solid build and super versatile piece of kit given its size, perfect for desktop use. Discontinued by spritzer to streamline his offerings, I daresay theres nothing better at this form factor. Internal voltage select currently set to 120V but can be adjusted for the buyer as needed prior to shipping. Old blurb from spritzer:I have the mini KGSSHV’s in stock now. This is a new version with a redesigned power supply. The basic topology is the same but with a new layout for better thermal performance and more capacitance to improve performance. Silver front panels on these and with an orange power LED. Standard mini specs so they run at +/-400V and the current through the output stage is set at 10mA so it runs pretty warm. It uses the 2SA1968 current sources which gives a more stable circuit with a slightly sweeter tone. Also available now is the KGSSHV mini in black. Uses my signature orange power led which looks stunning on the black front panel. Otherwise these are identical to the silver units. Shipping is free to US/Canada, other destinations please message me for a quote. For potential price adjustments, can contact me as well. Thanks for looking!

Selling a Mjölnir / Mjolnir Audio KGSSHV Mini Electrostatic Amp | For Parts/Repair | Blown Channel. Serial #48. 117VAC. Handmade in Iceland. Bought directly from Spritzer on his website. Original owner. The damage was caused by user error. The right channel was overbiased and subsequently blew a few components on the right circuit board and took out a driver on Stax headphones. The extent of damage is beyond my capabilities to repair and I dont have the time to repair it. This amplifier / energizer was used a lot. Ive unplugged everything at the front panel. The left channel was still functioning at the time of failure. The amp fuses never blew either. Notice the Stax headphone jack is removed because of overuse. It was falling apart. Screw holes for the headphones jack and power button need to be re-tapped / re-threaded as there is damage. Theres a missing screw for the power button chassis. The amplifier case itself has a handful of cosmetic scrapes. See the photos. There were small tweaks made to the amplifier, such as duct seal compound (removed) to steady the large PSU caps, soldered crimp connections at the power plug because they kept loosening, and a green LED. There are plenty of exotic electronic parts in this amplifier, such as a Keen Ocean toroidal transformer, an Alpha 4 Gang potentiometer, high voltage PSU capacitors, 2SC4686A transistors, 2SA1968 transistors, and more. Im not an electrical engineer so I cannot answer specifics about the design.

Mjolnir Audio KGSSHV. Its fully functional in like new condition. Selling to thin out my collection for a move. No returns
