Welcome, but you probably should have started a new thread for your request.
The part number you listed 007-6011-00 is for a power supply diode. Any silicon diode rated for at least 100 volts and 3 amps should work fine as a replacement.
Have a 9.8 of 10 100 with it's original Jensens & covers.it's a '68 and have know the amp since new...the reverb does not turn off all the way unless you have the foot switch (i do not) i had it checked and was told thats the way the circuit was set up...i think they are wrong.but nevertheless this one has NO ciggie burns,tears in the grill work or any rips or tears on the tuck & roll...the casters show their true unpitted chrome...there is pattina (a nice copper color)on the handles and the ports have sucumbed to a nice aluminum (hence the 9.8 rating)this amp is STUPID clean...not pricey...you pick up or arrange for shipping...thanks for your consideration...jim (barring pattina it is museum quality)
