For Sale Tubelab TSE-II 45 Amp with volume control 230V

[Fuzzbox]

Tubelab TSE-II 45 amplifier built by myself approximately 18 months ago. I’m an experienced builder, (hi-fi and guitar amps), based in London, UK.

** NOW SOLD **

Valves are a GZ34 rectifier in the power supply with a pair of 5842/417A input valves driving a pair of 45 output valves. The 45’s are DC heated and put out about 2W. Single input connection with a high quality volume attenuator. Housed on a 3mm gold anodised aluminium top from Front Panel Express mounted in a 12mm solid walnut case.

The valves are manually biased, (only required should you change them). It’s a trivial task but you will need a multimeter and a screwdriver. There are test points available and adjustable via holes in the top plate.

• Monolith Magnetics SX-1 NanoX nanocrystaline amorphous 5K output transformers, 4/8/16ohm secondaries
• Monolith Magnetics custom power transformer, 230/240V primaries, (no 115V tap)
• Monolith Magnetics custom choke
• Volume control via shunt 23 stepped attenuator, (Takman metal film/Charcroft Z-Foil/Seiden 2 pole 23-way switch)
• Silver wiring (Neotech NEI-1002 on the input, Mundorf silver/gold elsewhere), silver solder
• WBT silver RCA input and speaker output jacks
• Furutech rhodium IEC outlet
• ASC X386S oil filled capacitor in the power supply
• Passive components are a mix of Mundorf/Audio Note capacitors, Amtrans AMRG/Mills/Kiwame resistors
• Dimensions: 44.5cm wide, 34.5cm deep, 22.5cm height
• Weight: 13kg

I used it as my main amp for almost a year fed directly from a DAC with great results, absolutely silent on my 102dB horn speakers and easily drives them to room shaking levels. Parts cost without valves was approximately £2800, happy to supply a bill of materials.

Asking price includes the following valves, (these are not the ones in the photos):

• 1x JJ GZ34 rectifier
• 2x Western Electric 417A (NOS with low hours)
• 2x RCA 45 (NOS with low hours, ST type)

Happy to demo and of course collection is very welcome, (London UK).
