olegau Posted November 10, 2018 Share Posted November 10, 2018 SOLD Item: McChanson MarzE KT88/EL34 Tube Amplifier Location: Melbourne, St Kilda Price: 750 firm Item Condition: very good Reason for selling: too many amps Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: For sale is this 16W KT88 tube amplifier, built in Australia by Eric Chan. Single Ended amp, so the power around 8W to 10W for 6L6GC / 300B amps. For KT88 it is around 16 W and a bit less for EL34. There is a switch to use it either UL or Triode mode. The handle to the back is Triode, the handle to the front is UL ( Ultral Linear ) mode. Output is lower for Triode mode. You should try both modes to see which one mode you prefer. I used this amp with my Focal 1007S speakers (sensitivity 89db, 8 ohms). The volume knob was at 8 o'clock only because higher volume is too loud for my room. "This is the last McChanson MarzE amp, which has MarzE output transformers which costs many times more than timE transformer based amp. This is one of the top of the range model Eric produced and Eric (producer of McChanson Tube Amps) cannot produce this specific model because he cannot source this beautiful transformers any longer. The chassis has been upgraded to all silver. They are rock solid and heavy. The coupling capacitors are Russian PIO (Paper In Oil) , the attenuator is an ALPS stepped unit, the rectifier is a Mullard 5AR4, plus other upgraded parts inside. It originally cost $1700 and it comes with extra tubes for tube rolling. Currently installed are a pair of Genalex Gold Lion Russian KT 88's. Spare addition tubes included: 2 x Matched Pair GE USA 6EM7/6EA7 Light Grey Plate Coin Base Vacuum Tubes 129/75% 2 x Matched Pair 6P3S-E Russia. Erick wrote me: Russian 6P3S-E is good, it is standard for my 6L6GC amps. set the bias to 50mV OK, but you can try to increase up to 60mV to see how the sound improves, if any. Documents regarding bias adjustments will be provided. Adjustments can be done easily by non experienced people. The amp enables you to have tubes rolling fun. The amp is compatible in using all other 6L6 family tubes: 6L6 (metal), 6L6G, GA, GB and 5881, KT66, KT77, KT88, also EL34and 6P3S-E.

Paul-H Posted November 11, 2018 Share Posted November 11, 2018 This is a beautiful amp made by Eric. I can testify that these marzE transformers do resolve a great deal of detail in the upper frequencies, since I have one of these too. This is a bargain price for a beautiful hand crafted quality amp. Good luck with the sale. Link to comment Share on other sites More sharing options...

olegau Posted November 11, 2018 Author Share Posted November 11, 2018 The offer is pending for a couple of days. The offer for selling is not relating the quality of the amp. It is a nice looking and sounding amp, nothing wrong. I wanted to keep it and even recently bought spare tubes. As an electronic repair technician I opened it to look what is inside and was surprised by quality design and connections. I could not find any imperfection. All done well and accurately. Next to me is an opened Chinese amp. I am laughing. Where they got so tiny wires are connecting parts inside? Probably from a telephone wire? Its thickness is less 1mm! The Cheese filament voltage is 7V. Whereas the McChanson has 6.7V, factory comply. The mux limit is probably 6.9V, perfect is 6.3V. This tiny over voltage limit ( maximum too) will decrease tube life by minimum 10%. Fuse is not exist! Volume control, case....:):):) The McChanson case is solid, like a safe. it made of aluminium but very heavy, approximately 20kg, due of transformers. 2 Link to comment Share on other sites More sharing options...
