walang kit sir, assembled na? baka meron ka pic para makita ng newbies...
I have a russian close equivalent 6F5P ,but the 6F3p is more closer to 6BM8.
People who don't like capacitors, are they Purists o Foolish?....

there are many sites that offer kits.....tube depot is one...https://www.tubedepot.com/t/diy-central/kits-tube-amp/hifi-tube-amp-kits

depending on your skill level you can choose any one of those...
or you can build from scratch using vintage designs...
my current favorite is the mullard 5-20.....https://www.google.com.ph/search?q=mullard+5-20&oq=mullard+5-20&aqs=chrome..69i57&sourceid=chrome&es_sm=93&ie=UTF-8

Hello po, I'm a newbie in electronics but I am a great listener and reader. My major is Mathematics but since mahilig ako tumugtog ng gitara and keyboard, I became interested in DIY Audio. I started studying electronics via TESDA EPAS Short Course and since matutuhan ko kung ano ang resistors, caps, transistors, etc. three months ago, nag'build na ako ng DIY Guitar pedals like MXR Distortion+ clone tsaka Eighteen ng RunOffGroove.com. Then I read about tube amps, sino po ba makakatulong sakin mag'build ng isa? I need a simple guitar tube amp that can drive a Celestion Greenback 12" 25 Watts Speaker. Hindi ko muna desire yung maraming controls and effects as long as magagamit ko sya for clean and distorted sounds. Gusto ko sana yung clone ng Marshall 18 watt o kaya Orange Tiny Terror clone kaya lang ang hirap makipag'discuss sa foreign people tsaka gusto ko yung resources matatagpuan lang sa Pinas. Thank you po sa makakatulong.
