Cheapest Tube Amplifier

It has been some time we update our blog. A lot of activities are happening at the background that tied up all our time to do some write up. Transformers order, custom amplifier orders and etc are lining up back to back and kept us busy until October-November'14.

Below is the entry level amplifier that we are building for a tube beginner with all our new old stock components from our storeroom that has been kept for some time. Those with sharp eyes will notice that even the choke is not from us. (Blush!) Well, those were the transformers we bought for comparisons or benchmark to ensure our stuff is equal or better in quality when compared to the major brands. Since they're sitting idle, we say, why not just get them utilized?! Nothing much to shout aloud with but it is still decently built.

Entry level tube amplifier

•  NOS Russian Paper In Oil coupling capacitor
• Dual Nippon Chemicon B+ PSU capacitor for EL34
• Dual LSHC electrolytic for 6SL7
• Dual Sonicap for high frequency B+ filtering
• Pseudo choke input power supply
• 6SL7 drive EL34 / 6CA7

While working on the entry level EL34 amplifier, we need to start another project soon - Level 2 PCL85  single ended tube amplifier with ALIS-5SE Ultimate output transformer. This will be the highest end PCL85 ever built. We will share more when work starts.

Below are the Z11 power transformer and Z11 power choke that will be used for the Level 2 PCL85 amplifier.

Then after this will be our 300B Level 2.5 mono-blocks with Tung-Sol and Telefunken driver tubes down the road (Kev, yes, yours!). It's the busy time of the year... :)
