A schematic of the SE KT88 tube amplifier that I have built is EL34/6L6GC UL Mini Single Ended Amplifier's schematic replaced power transformer more big one finally connected as Triode with EL34, KT88/6550 sound like EL156/KT88 SE Amplifier triode connection.very clear but output transformer are small 7 Wrms so I got around 6.5Wrms with 6550/KT88.and small transformer so does not get good low edge. untill 30Hz 0dB EL34 is very famous tube and great for power tube amplifier. The circuit above is complete circuit contains tube amplifier circuit diagram and power supply circuit diagram. To make the stereo channel amplifier, build the similar amplifier circuit only and connect to the power supply using parallel connection with another same amplifier. I’m working on some ideas for a single ended EL34 amp and have a few questions. Would greatly appreciate your input.

Here are some notes and photographs of a single-ended (SE) KT88 tube amplifier which I recently built. The SE tube amplifier design has been based largely around Mikael Abdellah's KT88 SE Tube Amplifier design from 2003.

Auto-bias … The complete schematic to implement the separated grid voltage could be found here. Before to insert the EL34 tubes in the sockets switch on the amplifier with only the two little tubes (12AX7/ECC83 and 5814/ECC82) and set the trimmers to get about -50V from the grids of the EL34 and the ground. Amp schematic with 4x ECC83 & 2x EL34, 70-21-11 (Unicord, 1970).

Iklan Tengah Artikel 2. Nov 12, 2017 - A DIY Single-Ended (SE) Tube Amplifier Project that is compatible with KT88 / 6L6 / EL34 / 6CA7 tubes. A 6N1P dual triode is used to drive the output stage. 2015-02-01 · EL34 Triode Connection Non-NFB Push-Pull with Hashimoto Transformers - Project #1. This amplifier was originally featured on the February 2003 Issue of the "High-Fidelity Audio: Radio Technology" by Mr. Tadaatsu Atarashi.

The preamp is pretty much nailed down.

The JJ EL34's are very sweet and have that old European EL34 tone with extremely detailed mids and they transition smoothly when over driven.

Incidentally, although the El34 data sheet claims the maximum quiescent anode voltage is 800V, this applied to current production in the 1960's. Note on 17th Mar 2013 : This board is now 2mm thickness for even better mechanical strength and reliability !!
