What can be made with these tubes?
I have the following tubes;
6SC7 6SL7 6SN7 5Y3 8552 Is there any transmitters or receivers that can be built with these? If not TXor RX, what can be done with them? Kirk Mohror K7EKM --- Outgoing mail is certified Virus Free.

Hm.... this should be on the Extra exam
 6SC7: VFO 6SN7: transmitter final 5Y3: Power supply rectifier 6SL7: 1-tube regen 8552: damfino! I'd say you could build a very primitive transciever.

Behold, The Eternal Squire signalled from keyed 4-1000A filament:
8552: damfino! 8552 = 12V filament 6146B http://hereford.ampr.org/cgi-bin/tube?tube=8552 So, use the 6SL7 for a driver ;-) -- Gregg *It's probably useful, even if it can't be SPICE'd* http://geek.scorpiorising.ca |

Others have mentioned uses for these tubes. What they haven't mentioned is
that you will need a power supply delivering DC somewhere in the 150 to 250 volt range. It is absolutely vital that this supply have a transformer to isolate you from the 115 V AC mains. Otherwise you'll likely kill someone or yourself, since on side of the AC line is connected to ground and the other is HOT with respect to every grounded object. Junk boxes all across the world may be full of these transformers, but you may have trouble finding one. In that case you could use a couple of 115 to 12-or-so volt transformers. One to go from 115 to 12 V AC, the other connected "backwards" to go from 12 V AC back to 115 V AC. Now you have 115 V AC with neither side grounded - much safer. |

Just to add, if you only need ~15 watts for your project, bathroom shaver isolation transformers hooked up in a FW doubler are great for this too. You can get them from building surplus or second hand stores for 2-$5. -- Gregg *It's probably useful, even if it can't be SPICE'd* http://geek.scorpiorising.ca |
