Good morning, I am restoring a Macintosh SE/30 that I received as a gift. The case is the following, the motherboard did not have the Motorola MC68030rc16 shock type processor (someone removed it to sell the gold) I bought the same one but the seller sent me a MC68030RC30C, instead of the MC68030rc16B, I assumed that there would be no problem in that in instead of 16mhz I had 30mhz. I recap the board and got it working. The equipment works but the resistor R29 (12 Ohm, 2w) of the analog board gets very hot!!! and I'm afraid it might burn. Do you think that the increase in temperature in this resistor could be due to the difference in MHz between the original processor and the one that I have installed? Greetings
