Late ‘60 brings a lot of memories
CB400F = 4 cylinders.
CB400 = 2 cylinders.

Anything lesser than 400, “sissy” ZM would says.

Cheers

Ahhh the memories… My first road bike was a CB550F the little inline 4s were so cool. Such a fine machine, I still love most everything Honda based on that experience. The last was a H2 Kawasaki not as reliable or well behaved but the feeling that you were just on the edge of smashing yourself to bits was irresistible. I see all of the dandies riding around on their brandy new traction control super bikes and think man… you kids don’t even get it.

1968 Honda CB250. The black triangle on the side of the gas tank is a bit unique.


The 150 had a black square on the side of the gas tank. The 350 black triangle had a rounded hypotenuse.

Interesting. The 250 and 305 look very much alike. It appears that the 305 cylinders lean forward at and angle while the 250 cylinders are upright.

My motorcycle is a 2003 Yamaha FJR1300. 145 horsepower. It can do the 1/4 mile in less than 10 seconds.

A few weekends ago, I attended a maintenance event where we disassembled the bikes enough for a valve clearance check. Rotating the rear wheel to advance the valve train is quite an experience.

Hi, I have been following this thread for a couple weeks and are very interesting in building this amp. I have a question for the experts please. I have a pair of transformers with 49v secondary and some 35000uf/75v caps I would like to use. Theoretically it should yield 69v DC (49x1.4 cap input). With a safety margin of only 6v, is it safe enough to use these caps?

Psu voltage is + 60 Volts (not 69V)
75V rated capacitors are OK for Schade 50Watt's

Thanks for your input.

But the transformer secondary is measured at 49v AC, DC can then be up to 69v (49x1.4)? Maybe it will come back down when the circuit start to draw power?
